Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 A over the full range of output current, 0 mA to 750 mA). These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 1 A at TJ = 25C. The RESET output of the TPS777xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS777xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. Power good (PG) of the TPS778xx is an active high output, which can be used to implement a power-on reset or a low-battery indicator. The TPS777xx and TPS778xx are offered in 1.5-V, 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V for the TPS77701 option and 1.2 V to 5.5 V for the TPS77801 option). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS777xx and TPS778xx families are available in 8-pin SOIC and 20-pin PWP packages.

Conventional LDO regulators use a pnp pass element, the base current of which is directly proportional to the load current through the regulator (IB = IC/). The TPS777xx and TPS778xx use a PMOS transistor to pass current; because the gate of the PMOS is voltage driven, operating current is low and invariable over the full load range. Another pitfall associated with the pnp-pass element is its tendency to saturate when the device goes into dropout. The resulting drop in forces an increase in IB to maintain the load. During power up, this translates to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation. The TPS777xx and TPS778xx quiescent currents remain low even when the regulator drops out, eliminating both problems. The TPS777xx and TPS778xx families also feature a shutdown mode that places the output in the high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to 2 A. If the shutdown feature is not used, EN should be tied to ground. minimum load requirements The TPS777xx and TPS778xx families are stable even at zero load; no minimum load is required for operation. FB--pin connection (adjustable version only) The FB pin is an input pin to sense the output voltage and close the loop for the adjustable option . The output voltage is sensed through a resistor divider network to close the loop as it is shown in Figure 26. Normally, this connection should be as short as possible; however, the connection can be made near a critical circuit to improve performance at that point. Internally, FB connects to a high-impedance wide-bandwidth amplifier and noise pickup feeds through to the regulator output. Routing the FB connection to minimize/avoid noise pickup is essential. external capacitor requirements An input capacitor is not usually required; however, a ceramic bypass capacitor (0.047 F or larger) improves load transient response and noise rejection if the TPS777xx or TPS778xx are located more than a few inches from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transients with fast rise times are anticipated. Like all low dropout regulators, the TPS777xx and TPS778xx require an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 10 F and the ESR (equivalent series resistance) must be between 50 m and 1.5 . Capacitor values 10 F or larger are acceptable, provided the ESR is less than 1.5 . Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described previously. 15 www.ti.com SLVS230G - SEPTEMBER 1999 - REVISED JANUARY 2004 APPLICATION INFORMATION external capacitor requirements (continued) 6 VI 16 IN RESET/ PG IN 14 OUT 13 EN OUT 7 C1 0.1 F 5 GND RESET/PG 250 k VO + Co 10 F 3 Figure 25. Typical Application Circuit (Fixed Versions) programming the TPS77x01 adjustable LDO regulator The output voltage of the TPS77x01 adjustable regulator is programmed using an external resistor divider as shown in Figure 26. The output voltage is calculated using: V O +V 1 ) R1 R2 ref (1) Where: Vref = 1.1834 V typ (the internal reference voltage) Resistors R1 and R2 should be chosen for approximately 10-A divider current. Lower value resistors can be used but offer no inherent advantage and waste more power. Higher values should be avoided as leakage currents at FB increase the output voltage error. The recommended design procedure is to choose R2 = 110 k to set the divider current at approximately 10 A and then calculate R1 using: R1 + V V O *1 ref R2 (2) OUTPUT VOLTAGE PROGRAMMING GUIDE TPS77x01 VI 0.1 F IN RESET/ PG 250 k 1.7 V 0.9 V Reset or PG Output EN OUT VO R1 FB / NC GND Co OUTPUT VOLTAGE R1 UNIT 2.5 V 121 110 k 3.3 V 196 110 k 3.6 V 226 110 k 4.75 V 332 110 k R2 Figure 26. TPS77x01 Adjustable LDO Regulator Programming 16 R2 www.ti.com SLVS230G - SEPTEMBER 1999 - REVISED JANUARY 2004 APPLICATION INFORMATION reset indicator The TPS777xx features a RESET output that can be used to monitor the status of the regulator. The internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal regulated value, the RESET output transistor turns on, taking the signal low. The open-drain output requires a pullup resistor. If not used, it can be left floating. RESET can be used to drive power-on reset circuitry or as a low-battery indicator. RESET does not assert itself when the regulated output voltage falls outside the specified 2% tolerance, but instead reports an output voltage low relative to its nominal regulated value (refer to timing diagram for start-up sequence). power-good indicator The TPS778xx features a power-good (PG) output that can be used to monitor the status of the regulator. The internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or used as a low-battery indicator. regulator protection The TPS777xx and TPS778xx PMOS-pass transistors have a built-in back diode that conducts reverse currents when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate. The TPS777xx and TPS778xx also feature internal current limiting and thermal protection. During normal operation, the TPS777xx and TPS778xx limit output current to approximately 1.7 A. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds 150C(typ), thermal-protection circuitry shuts it down. Once the device has cooled below 130C(typ), regulator operation resumes. 17 www.ti.com SLVS230G - SEPTEMBER 1999 - REVISED JANUARY 2004 APPLICATION INFORMATION POWER DISSIPATION AND JUNCTION TEMPERATURE Specified regulator operation is assured to a junction temperature of 125C; the maximum junction temperature should be restricted to 125C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or equal to PD(max). The maximum-power-dissipation limit is determined using the following equation: P T max * T A + J D(max) R qJA Where: TJmax is the maximum allowable junction temperature. RJA is the thermal resistance junction-to-ambient for the package, and is calculated as 1 derating factor from the dissipation rating tables. TA is the ambient temperature. The regulator dissipation is calculated using: P D + V *V I O I O Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the thermal protection circuit. 18 PACKAGE OPTION ADDENDUM www.ti.com 30-Jul-2011 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
