Features

1.5 V to 5.5 V, selectable in 0.1 V steps. ±1.0% 120 mV typ. (3.0 V output product, IOUT = 300 mA) During operation: 80 µA typ., 160 µA max. During shutdown: 0.1 µA typ., 1.0 µA max.
• High peak current capability: 800 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)
*1 Ensures long battery life.
• Built-in ON/OFF circuit:
• Low ESR capacitor can be used: A ceramic capacitor of 4.7 µF or more can be used for the output capacitor. 70 dB typ. (at 1.0 kHz)
• High ripple rejection: Overcurrent of output transistor can be restricted.
• Built-in overcurrent protector:
• Built-in thermal shutdown circ.
