Stability

Assuming, the following conditions:

The APU1150 requires the use of an output capacitor as

part of the frequency compensation in order to make the

regulator stable. Typical designs for the microprocessor

applications use standard electrolytic capacitors with

typical ESR in the range of 50 to 100mΩ and an output
