AP7354D-12FS4-7

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

The AP7354D-12FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a precise 1.2V output with a maximum guaranteed current of 150mA. It operates within an input voltage range of 2.0V to 5.5V and maintains a tight output voltage accuracy of ±1%. The device features an ultra-low quiescent current of 0.25µA and a typical standby current of 0.02µA when the enable pin is deactivated. Packaged in an X2-DFN1010-4 (Type B) footprint, it includes an integrated active output discharge circuit for rapid shutdown. The component supports an operating ambient temperature range from -40°C to +85°C.

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

Verify that the specific part number suffix FS4 corresponds to the X2-DFN1010-4 package type and D indicates the presence of the output discharge feature. Confirm compliance with RoHS and halogen-free requirements as specified by the manufacturer. Ensure ordering quantities align with standard tape and reel packaging configurations provided by authorized distributors.

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

Select this component when a compact form factor and minimal standby current are critical for system longevity. The inclusion of the output discharge function distinguishes it from non-discharge variants, making it suitable for applications requiring fast power-down sequences. Verify that the required 1.2V output aligns with the target load specifications and that the 150mA current capacity meets peak demand scenarios.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the AP7354 series of ultra-low quiescent current LDO regulators. The 'D' suffix specifically denotes the version equipped with an active output discharge resistor, while 'FS4' identifies the X2-DFN1010-4 physical package.
