ACT4012A 5V/1.5A Output Application

: D1 is a 30V, 2A Schottky diode with low forward voltage, an IR 20BQ030 or SK23 equivalent. C4 can be either a ceramic capacitor

The SP-Cap is based on aluminum electrolytic capacitor technology, but uses a solid polymer electrolyte and has very stable capaci-

tance characteristics in both operating temperature and frequency compared to ceramic, polymer, and low ESR tantalum capacitors.
