AP7346D-2825FS6-7

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

The AP7346D-2825FS6-7 is a dual high accuracy current limit low dropout regulator based on CMOS process. It provides fixed output voltages of 2.8V and 2.5V with ±1% accuracy. The device operates within an input voltage range of 1.7V to 5.25V and delivers up to 130mA per channel. Key electrical characteristics include a ripple rejection of 75dB at 1kHz, low output noise of 60µVrms from 10Hz to 100kHz, and quiescent current as low as 35µA. Dropout voltage varies by output level, reaching a maximum of 0.59V at 120mA for lower outputs.

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

What is the function of the EN pins?

The EN1 and EN2 pins independently control the activation of Channel 1 and Channel 2 respectively. Driving these pins high enables the output, while pulling them low shuts down the regulator.

How does the device handle short circuits?

When VOUT pins are shorted to ground, short-circuit protection triggers and clamps the output current to approximately 60mA, protecting the regulator from overheating and damage.
