AN77L00/AN77L00M Series
3-pin Low Power Loss Voltage Regulato r (100mA Type)
s Overview
The AN77L00/AN77L00M series is a stabilized constant voltage power supply with a low input/output voltage(0.3V max.). It is suitable for the low-voltage equipment using batteries, and consumer/industrial equipment with great fluctuation of the supply voltage. A wide range of output voltage is available from 3V through 10V.
