AP7354 150mA ULTRA-LOW QUIESCENT CURRENT LDO WITH ENABLE Description Pin Assignments The AP7354 is a low dropout regulator with high output voltage accuracy. The AP7354 includes a voltage reference, error amplifier, (Top View) (Top View) current limit circuit, and an enable input to turn it on/off. With the GND integrated resistor network, fixed output voltage versions can be 3 delivered. VIN 1 5 VOUT With its ultra-low quiescent current, the AP7354 is well-suited for low- 2 GND power handheld, wearable devices, and other battery-operated 1 2 3 4 EN NC devices requiring an extended time period until new battery IN V VOUT replacement. SOT23 SOT25 The AP7354 is available in SOT23, SOT25, and X2-DFN1010-4 (Type B) packages.
