Product S1F78A12/15 S1F78B20/17
Regulator extra-low current consumption
This which achieved high ripple removal rate, high load response, high precision while substantially reducing current consumption using EPSON's unique circuit technique. provided with built-in automatic mode selector function, which makes self-determination output current automatically switches current consumption mode when load applied. Therefore, external mode switching required current consumption achieved. adopts ultra-compact package VSON-6Pin (1.6mm 1.6mm) contribute space savings. addition "S1F78A12" min. self-current consumption "S1F78A15" providing power consumption high-speed response, will provide lineup products such "S1F78B20" high ripple removal rate, "S1F78B17" which packages should applied WCSP (Wafer level CSP) "S1F78B16: VOUT 0.9V less" which supports voltage.
