AP7340D-285FS4-7

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

The AP7340D-285FS4-7 is a CMOS-based low dropout regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 2.85V with an accuracy of ±1%. The device guarantees an output current of 150mA and operates within an input voltage range of 1.7V to 5.25V. Key electrical characteristics include a quiescent current as low as 35µA, ripple rejection of 75dB at 1kHz, and output noise of 60µVrms from 10Hz to 100kHz. It features short circuit protection and is housed in an X2-DFN1010-4 package.

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

What is the function of the EN pin?

The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low puts the device into shutdown mode.

Does this part have an output discharge feature?

Yes, the 'D' in AP7340D indicates that the device includes an N-channel auto-discharge resistor to pull down the output voltage when disabled.
