AP7342D-1828FS6-7

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

The AP7342D-1828FS6-7 is a dual low-dropout regulator from Diodes Incorporated, featuring two independent channels with fixed output voltages of 1.8V and 2.8V. It operates within an input voltage range of 1.7V to 5.25V and guarantees an output current of 150mA per channel. The device provides high ripple rejection of 75dB at 1kHz and maintains low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified as low as 35µA. It includes integrated enable inputs for each channel and is housed in an X2-DFN1212-6 package.
