... Figure 3 - Schematic showing connection for best load regulation Stability The US1150 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. Typical designs for the microproces- sor applications use standard electrolytic capacitors with typical ESR in the range 100 m and an output capacitance of 500 to 1000uF ...
