LP3883 www.ti.com SNVS223F - NOVEMBER 2002 - REVISED APRIL 2013 LP3883 3A Fast-Response Ultra Low Dropout Linear Regulators Check for Samples: LP3883 FEATURES DESCRIPTION * * * * * * * * The LP3883 is a high-current, fast-response regulator which can maintain output voltage regulation with minimum input to output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages: Vbias provides voltage to drive the gate of the N-MOS power transistor, while Vin is the input voltage which supplies power to the load. The use of an external bias rail allows the part to operate from ultra low Vin voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. 1 2 Ultra Low Dropout Voltage (210 mV @ 3A typ) Low Ground Pin Current Load Regulation of 0.04%/A 60 nA Typical Quiescent Current in Shutdown 1.5% Output Accuracy (25C) TO-220, DDPAK/TO-263 Packages Over Temperature/over Current Protection -40C to +125C Junction Temperature Range APPLICATIONS * * * * * * * DSP Power Supplies Server Core and I/O Supplies Linear Power Supplies for PC Add-in-Cards Set-Top Box Power Supplies Microprocessor Power Supplies High Efficiency Linear Power Supplies SMPS Post-Regulators The fast transient response of these devices makes them suitable for use in powering DSP, Microcontroller Core voltages and Switch Mode Power Supply post regulators.

Operating ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions. If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin. The machine model is a 220 pF capacitor discharged directly into each pin. The machine model ESD rating of pin 5 is 100V. At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values. J-A for TO-220 devices is 65C/W if no heatsink is used. If the TO-220 device is attached to a heatsink, a J-S value of 4C/W can be assumed. J-A for DDPAK/TO-263 devices is approximately 40C/W if soldered down to a copper plane which is at least 1.5 square inches in area. If power dissipation causes the junction temperature to exceed specified limits, the device will go into thermal shutdown.

OUTPUT CAPACITOR At least 4.7F of output capacitance is required for stability (the amount of capacitance can be increased without limit). The output capacitor must be located less than 1 cm from the output pin of the IC and returned to a clean analog ground. The ESR (equivalent series resistance) of the output capacitor must be within the "stable" range as shown in the graph below over the full operating temperature range for stable operation. 10 COUT ESR (:) 1.0 COUT = 4.7PF STABLE REGION 0.1 COUT = 100PF .01 .001 0 1 2 3 LOAD CURRENT (A) Figure 33. Minimum ESR vs Output Load Current Tantalum capacitors are recommended for the output as their ESR is ideally suited to the part's requirements and the ESR is very stable over temperature. Aluminum electrolytics are not recommended because their ESR increases very rapidly at temperatures below 10C. Aluminum caps can only be used in applications where lower temperature operation is not required. A second problem with Al caps is that many have ESR's which are only specified at low frequencies. The typical loop bandwidth of a linear regulator is a few hundred kHz to several MHz. If an Al cap is used for the output cap, it must be one whose ESR is specified at a frequency of 100 kHz or more. Because the ESR of ceramic capacitors is only a few milli Ohms, they are not suitable for use as output capacitors on LP388X devices. The regulator output can tolerate ceramic capacitance totaling up to 15% of the amount of Tantalum capacitance connected from the output to ground. OUTPUT "BYPASS" CAPACITORS Many designers place small value "bypass" capacitors at various circuit points to reduce noise. Ceramic capacitors in the value range of about 1000pF to 0.1F placed directly on the output of a PNP or P-FET LDO regulator can cause a loss of phase margin which can result in oscillations, even when a Tantalum output capacitor is in parallel with it. This is not unique to Texas Instruments LDO regulators, it is true of any P-type LDO regulator. The reason for this is that PNP or P-FET regulators have a higher output impedance (compared to an NPN regulator), which results in a pole-zero pair being formed by every different capacitor connected to the output. The zero frequency is approximately: Fz = 1 / (2 X X ESR X C) where * * ESR is the equivalent series resistance of the capacitor C is the value of capacitance (1) Submit Documentation Feedback Copyright (c) 2002-2013, Texas Instruments Incorporated Product Folder Links: LP3883 9 LP3883 SNVS223F - NOVEMBER 2002 - REVISED APRIL 2013 www.ti.com The pole frequency is: Fp = 1 / (2 X X RL X C) where * RL is the load resistance connected to the regulator output (2) To understand why a small capacitor can reduce phase margin: assume a typical LDO with a bandwidth of 1MHz, which is delivering 0.5A of current from a 2.5V output (which means RL is 5 Ohms). We then place a .047 F capacitor on the output. This creates a pole whose frequency is: Fp = 1 / (2 X X 5 X .047 X 10E-6) = 677 kHz (3) This pole would add close to 60 degrees of phase lag at the crossover (unity gain) frequency of 1 MHz, which would almost certainly make this regulator oscillate. Depending on the load current, output voltage, and bandwidth, there are usually values of small capacitors which can seriously reduce phase margin. If the capacitors are ceramic, they tend to oscillate more easily because they have very little internal inductance to damp it out. If bypass capacitors are used, it is best to place them near the load and use trace inductance to "decouple" them from the regulator output. INPUT CAPACITOR The input capacitor must be at least 4.7 F, but can be increased without limit. It's purpose is to provide a low source impedance for the regulator input. Ceramic capacitors work best for this, but Tantalums are also very good. There is no ESR limitation on the input capacitor (the lower, the better). Aluminum electrolytics can be used, but their ESR increase very quickly at cold temperatures. They are not recommended for any application where temperatures go below about 10C. BIAS CAPACITOR The 0.1F capacitor on the bias line can be any good quality capacitor (ceramic is recommended). BIAS VOLTAGE The bias voltage is an external voltage rail required to get gate drive for the N-FET pass transistor. Bias voltage must be in the range of 4.5 - 6V to assure proper operation of the part. UNDER VOLTAGE LOCKOUT The bias voltage is monitored by a circuit which prevents the regulator output from turning on if the bias voltage is below approximately 4V. SHUTDOWN OPERATION Pulling down the shutdown (S/D) pin will turn-off the regulator. Pin S/D must be actively terminated through a pull-up resistor (10 k to 100 k) for a proper operation. If this pin is driven from a source that actively pulls high and low (such as a CMOS rail to rail comparator), the pull-up resistor is not required. This pin must be tied to Vin if not used. POWER DISSIPATION/HEATSINKING A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of the application. Under all possible conditions, the junction temperature must be within the range specified under operating conditions. The total power dissipation of the device is given by: PD = (VIN-VOUT)IOUT+ (VIN)IGND where * IGND is the operating ground current of the device (4) The maximum allowable temperature rise (TRmax) depends on the maximum ambient temperature (TAmax) of the application, and the maximum allowable junction temperature (TJmax): TRmax = TJmax- TAmax (5) The maximum allowable value for junction to ambient Thermal Resistance, JA, can be calculated using the formula: 10 Submit Documentation Feedback Copyright (c) 2002-2013, Texas Instruments Incorporated Product Folder Links: LP3883 LP3883 www.ti.com SNVS223F - NOVEMBER 2002 - REVISED APRIL 2013 JA = TRmax / PD (6) These parts are available in TO-220 and DDPAK/TO-263 packages. The thermal resistance depends on amount of copper area or heat sink, and on air flow. If the maximum allowable value of JA calculated above is 60 C/W for TO-220 package and 60 C/W for DDPAK/TO-263 package no heatsink is needed since the package can dissipate enough heat to satisfy these requirements. If the value for allowable JA falls below these limits, a heat sink is required. HEATSINKING TO-220 PACKAGE The thermal resistance of a TO220 package can be reduced by attaching it to a heat sink or a copper plane on a PC board. If a copper plane is to be used, the values of JA will be same as shown in next section for TO263 package. The heatsink to be used in the application should have a heatsink to ambient thermal resistance, HA JA - CH - JC. (7) In this equation, CH is the thermal resistance from the case to the surface of the heat sink and JC is the thermal resistance from the junction to the surface of the case. JC is about 3C/W for a TO220 package. The value for CH depends on method of attachment, insulator, etc. CH varies between 1.5C/W to 2.5C/W. If the exact value is unknown, 2C/W can be assumed. HEATSINKING DDPAK/TO-263 PACKAGE The DDPAK/TO-263 package uses the copper plane on the PCB as a heatsink. The tab of these packages are soldered to the copper plane for heat sinking. The graph below shows a curve for the JA of DDPAK/TO-263 package for different copper area sizes, using a typical PCB with 1 ounce copper and no solder mask over the copper area for heat sinking. Figure 34. JA vs Copper (1 Ounce) Area for DDPAK/TO-263 package As shown in the graph below, increasing the copper area beyond 1 square inch produces very little improvement. The minimum value for JA for the DDPAK/TO-263 package mounted to a PCB is 32C/W. Figure 35 shows the maximum allowable power dissipation for DDPAK/TO-263 packages for different ambient temperatures, assuming JA is 35C/W and the maximum junction temperature is 125C. Figure 35.
