AP7354D-28FS4-7

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

The AP7354D-28FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a precise 2.8V output with a guaranteed maximum load current of 150mA. It operates within an input voltage range of 2.0V to 5.5V and features an ultra-low quiescent current of 0.25µA, dropping to 0.02µA in standby mode when the enable pin is deactivated. The device incorporates an integrated discharge resistor for rapid output capacitor discharge upon shutdown. Packaged in the compact X2-DFN1010-4 (Type B) format, it provides high output voltage accuracy of ±1% across the industrial temperature range of -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 RoHS compliance and halogen-free status requirements against project specifications. Ensure ordering quantities align with standard tape and reel packaging configurations provided by the manufacturer.

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

Select this component when system design demands minimal ground current during active operation alongside fast output discharge capabilities. The fixed 2.8V output eliminates external resistor networks, simplifying the bill of materials. Evaluate thermal dissipation constraints based on the junction-to-ambient resistance characteristic of the small outline package under expected ambient operating conditions.

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

This device belongs to the AP7354 series of low dropout regulators from Diodes Incorporated. The series offers multiple output voltage options ranging from 1.1V to 4.5V across various package types including SOT23, SOT25, and X2-DFN1010-4. The 'D' variant specifically includes an internal discharge path not present in the standard AP7354 version, enhancing its utility in applications requiring strict power management sequences.
