Simple Micro Power Supply Circuit Diagram

This is simple micro power supply circuit diagram. The circuit uses a CA3440 BiMOS op amp and CA3086 transistor array. The no-load current from 5-volt supply is 1.5 µ A. Load current can go as high as 200 µ and still maintain output voltage regulation within 0.05%.
