1MOTOROLA ANALOG IC DEVICE DATA

These voltage regulators are monolithic integrated circuits designed asfixedvoltage regulators for a wide variety of applications including local,oncard regulation. These regulators employ internal current limiting,thermal shutdown, and safearea compensation. With adequate heatsinkingthey can deliver output currents in excess of 1.0 A. Although designedprimarily as a fixed voltage regulator, these devices can be used withexternal components to obtain adjustable voltages and currents. Output Current in Excess of 1.0 A 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

APPLICATIONS INFORMATIONDesign Considerations

The MC7800 Series of fixed voltage regulators aredesigned with Thermal Overload Protection that shuts downthe circuit when subjected to an excessive power overloadcondition, Internal Short Circuit Protection that limits themaximum current the circuit will pass, and Output TransistorSafeArea Compensation that reduces the output shortcircuit current as the voltage across the pass transistor isincreased.

In many low current applications, compensationcapacitors are not required. However, it is recommendedthat the regulator input be bypassed with a capacitor if theregulator is connected to the power supply filter with long

wire lengths, or if the output load capacitance is large. Aninput bypass capacitor should be selected to provide goodhighfrequency characteristics to insure stable operationunder all load conditions. A 0.33 F or larger tantalum,mylar, or other capacitor having low internal impedance athigh frequencies should be chosen. The bypass capacitorshould be mounted with the shortest possible leads directlyacross the regulators input terminals. Normally goodconstruction techniques should be used to minimize groundloops and lead resistance drops since the regulator has noexternal sense lead.

The MC7800 regulators can also be used as a current source whenconnected as above. In order to minimize dissipation the MC7805C ischosen in this application. Resistor R determines the current as follows:

For example, a 1.0 A current source would require R to be a 5.0 ,10 W resistor and the output voltage compliance would be the inputvoltage less 7.0 V.

The MC7800 series can be current boosted with a PNP transistor. TheMJ2955 provides current to 5.0 A. Resistor R in conjunction with the VBEof the PNP determines when the pass transistor begins conducting; thiscircuit is not short circuit proof. Input/output differential voltage minimum isincreased by VBE of the pass transistor.

The circuit of Figure 9 can be modified to provide supply protection againstshort circuits by adding a short circuit sense resistor, RSC, and anadditional PNP transistor. The current sensing PNP must be able to handlethe short circuit current of the threeterminal regulator. Therefore, afourampere plastic power transistor is specified.

DEFINITIONSLine Regulation The change in output voltage for a

change in the input voltage. The measurement is made underconditions of low dissipation or by using pulse techniques suchthat the average chip temperature is not significantly affected.

Load Regulation The change in output voltage for achange in load current at constant chip temperature.

Maximum Power Dissipation The maximum totaldevice dissipation for which the regulator will operate withinspecifications.

Quiescent Current That part of the input current that isnot delivered to the load.

Output Noise Voltage The rms ac voltage at the output,with constant load and no input ripple, measured over aspecified frequency range.

Long Term Stability Output voltage stability underaccelerated life test conditions with the maximum ratedvoltage listed in the devices electrical characteristics andmaximum power dissipation.
