AP7345D-285285RH4-7

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

The AP7345D-285285RH4-7 is a dual-channel low dropout regulator manufactured by Diodes Incorporated. It provides two independent fixed output voltages of 2.85V each, with a guaranteed maximum output current of 300mA per channel. The device operates within an input voltage range of 1.7V to 5.25V and features high power supply rejection ratio (PSRR) of 75dB at 1kHz. Quiescent current is typically 50µA when one channel is active, dropping to 1.0µA in standby mode. It includes integrated enable controls, thermal shutdown, and short-circuit protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix RH4-7 corresponds to the X2-DFN1612-8 package and tape & reel packaging configuration. Confirm that the dual 2.85V output designation matches the required system voltage rails. Ensure compatibility with RoHS 3 compliance standards if applicable to your manufacturing region. Cross-reference the datasheet revision DS41528 Rev. 1 - 2 for any recent updates to electrical characteristics or pin assignments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a compact dual-rail solution is required for portable devices. The X2-DFN1612-8 package offers a small footprint ideal for dense PCB layouts. Consider the 300mA per channel rating against peak load requirements. Evaluate the 75dB PSRR requirement for noise-sensitive sections like RF transceivers. Verify that the 1.7V minimum input voltage aligns with the available battery or bus voltage.
