AP7342D-3612FS6-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7342D-3612FS6-7 is a dual low-dropout regulator from Diodes Incorporated, packaged in an X2-DFN1212-6 footprint. It provides two fixed output voltages: Channel 1 delivers 3.6V and Channel 2 delivers 1.2V. The device guarantees a continuous output current of 150mA per channel with a wide input voltage range spanning 1.7V to 5.25V. Key electrical characteristics include a ripple rejection ratio of 75dB at 1kHz, a maximum dropout voltage of 0.29V at full load, and a typical quiescent current of 70µA when both channels are active.
