AP7354D-185FS4-7

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

The AP7354D-185FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a stable 1.85V output with a maximum current of 150mA. The device operates within an input voltage range of 2.0V to 5.5V and features ultra-low quiescent current of 0.25µA, dropping to 0.02µA in standby mode. It includes an enable pin for power control and built-in output discharge functionality. The component is housed in an X2-DFN1010-4 package and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific ordering suffix FS4 corresponds to the X2-DFN1010-4 package type before procurement. Confirm that the D suffix indicates the inclusion of the active output discharge feature, which distinguishes it from standard versions. Ensure compatibility with RoHS 3 compliance requirements if applicable to your manufacturing standards. Cross-reference the datasheet revision to confirm electrical characteristics match your design specifications.

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

Select this component when a compact surface-mount solution is required for low-power systems. The X2-DFN1010-4 package offers a small footprint suitable for space-constrained designs. The integrated discharge feature simplifies external circuitry compared to non-discharge variants. Consider the 1.85V fixed output level against system rail requirements to ensure proper logic or sensor interfacing without additional regulation stages.
