AP7354D-185W5-7

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

The AP7354D-185W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a regulated output voltage of 1.85 V with a guaranteed maximum output current of 150 mA. The device operates within an input voltage range of 2.0 V to 5.5 V and maintains an output voltage accuracy of ±1%. It features an ultra-low quiescent current of 0.25 µA and a typical standby current of 0.02 µA when the enable pin is deactivated. The component includes an integrated output discharge circuit, which actively pulls down the output voltage upon shutdown. It is housed in a surface-mount SOT-25-5 package.

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

What is the function of the 'D' suffix in the AP7354D-185W5-7 part number?

The 'D' suffix indicates that the device includes an integrated active output discharge circuit, which pulls the output voltage down when the enable pin is set to a low state.

How does the enable pin operate on this regulator?

Driving the EN pin high enables the regulator output, while pulling the EN pin low places the regulator into shutdown mode and activates the output discharge circuit.
