description/ordering information

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications.

These applications include on-card regulation for elimination of noise and distribution problems associated with

single-point regulation. Each of these regulators can deliver up to 1.5 A of output current. The internal

current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload.

In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain

adjustable output voltages and currents, and also can be used as the power-pass element in precision

regulators.

operation with a load common to a voltage of opposite polarity

In many cases, a regulator powers a load that is not connected to ground but, instead, is connected to a voltage

source of opposite polarity (e.g., operational amplifiers, level-shifting circuits, etc.). In these cases, a clamp

diode should be connected to the regulator output as shown in Figure 6. This protects the regulator from output

polarity reversals during startup and short-circuit operation.

reverse-bias protection

Occasionally, the input voltage to the regulator can collapse faster than the output voltage. This can occur, for

example, when the input supply is crowbarred during an output overvoltage condition. If the output voltage is

greater than approximately 7 V, the emitter-base junction of the series-pass element (internal or external) could

break down and be damaged. To prevent this, a diode shunt can be used as shown in Figure 7.
