(S) MOTOROLA Three-Terminal Positive Voltage Regulators These voltage regulators are monolithic integrated circuits designed as fixedvoltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safearea compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. Packages Output Current in Excess of 1.0A No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor SafeArea Compensation Output Voltage Offered in 2% and 4% Tolerance Available in Surface Mount D2PAK and Standard 3Lead Transistor @ Previous Commercial Temperature Range has been Extended to a Junction Temperature Range of -40C to +125C DEVICE TYPE/NOMINAL OUTPUT VOLTAGE MC7805AC MC7812C IBV LM340AT5 50V LM340T-12 MC7805C , MC7815AC LM340T-5 LM340AT-15 1SV MC7806AC 6.0V MC7815C MC7806G LM340T-15 MC7808AC MC7818AC 8.0V 18V MC7808C MC7818C MC7809C 9.0 V MC7824AC 24y MC7812AC 12V MC7824C LM340AT12 ORDERING INFORMATION Output Voltage Operating Device Tolerance Temperature Range Package MC78XXACT Insertion Mount LM340AT-XX 2% MC78XXACD2T Surface Mount Ty = 40 to +125C MC78XXCT Insertion Mount LM340T-XX 4% MC78XXCD2T Surface Mount Order this document by MC7800/D MC7800, MC7800A, LM340, LM340A Series THREE-TERMINAL POSITIVE FIXED VOLTAGE REGULATORS SEMICONDUCTOR TECHNICAL DATA T SUFFIX PLASTIC PACKAGE CASE 221A Heatsink surface connected to Pin 2. | 0 5 3 Pin 1.

The input voltage must remain typically 2.0 V above the output voltage even during the low point on the input ripple voltage. XX, These two digits of the type number indicate nominal voltage. * Cin is required if regulator is located an appreciable distance from power supply filter. ** Co is not needed for stability; however, it does improve transient response. Values of less than 0.1 uF could cause instability. XX indicates nominal voltage.

In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long Figure 7. Current Regulator a | Input MC7805 Ld 0.33 WF R Constant T Current to = Grounded Io Load The MC7800 regulators can also be used as a current source when connected as above. in order to minimize dissipation the MC7805C is chosen in this application. Resistor R determines the current as follows: 9.0 V lo= A + Ip lB = 3.2 mA over line and load changes. For example, a 1.0 A current source would require R to be a 5.0 Q, 10 W resistor and the output voltage compliance would be the input voltage less 7.0 V. Figure 9.

The MC7800 series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0 A. Resistor R in conjunction with the Vge of the PNP determines when the pass transistor begins conducting; this circuitis not short circuit proof. Input/output differential voltage minimum is increased by Vpe of the pass transistor. wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high~frequency characteristics to insure stable operation under all load conditions. A 0.33 uF or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Normally good construction techniques should be used to minimize ground loops and Jead resistance drops since the regulator has no external sense lead. Figure 8. Adjustable Output Regulator CTT Output Input \| VQ =7.0V to 20V VIN = Vo 22.0 V The addition of an operational amplifier allows adjustment to higher or intermediate values while retaining regulation characteristics. The minimum voltage obtainable with this arrangementis 2.0 V greater than the regulator voltage. Figure 10. Short Circuit Protection MJ2955 Rog oF Equiv. RSource Input 2N6049 or Equiv. Output XX = 2 digits of type number indicating voltage. The circuit of Figure 9 can be modified to provide supply protection against short circuits by adding a short circuit sense resistor, Roc, and an additional PNP transistor. The current sensing PNP must be able to handle the short circuit current of the three-terminal regulator. Therefore, a four-ampere plastic power transistor is specified. 14 MB 6367252 0100741 065 MOTOROLA ANALOG IC DEVICE DATAMC7800, MC7800A, LM340, LM340A Series Figure 12.
