Figure 8. Output Polarity-Reversal Protection Circuit
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., op amps, level-shifting circuits, etc.). In these cases, a clamp diode should be
connected to the regulator output as shown in Figure 8. This protects the regulator from output polarity reversals
during startup and short-circuit operation.

Occasionally, there exists the possibility that the input voltage to the regulator can collapse faster than the output
voltage. This could 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
employed as shown in Figure 9.
