AP7354-15FS4-7

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

The AP7354-15FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, delivering a precise 1.5V output with a guaranteed maximum load current of 150mA. It operates within an input voltage range of 2.0V to 5.5V and maintains high accuracy with a typical quiescent current of 0.25µA. The device features an enable control pin for power management and includes internal protections against short circuits and thermal overload. Packaged in the compact X2-DFN1010-4 (Type B) surface-mount format, it supports operation across an ambient temperature range of -40°C to +85°C.

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

Verify that the component matches the specific X2-DFN1010-4 package type and the non-discharge variant indicated by the absence of the 'D' suffix. Confirm RoHS compliance and lead-free status as specified in the manufacturer documentation. Ensure ordering quantities align with the standard tape and reel packaging requirements provided by the supplier.

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

Select this regulator when a fixed 1.5V supply is required with minimal ground current draw. The X2-DFN1010-4 package offers a small footprint suitable for space-constrained designs. Consider the dropout voltage characteristics at the expected load current to ensure adequate headroom from the input source. Verify that the application does not require an active output discharge feature, as this part lacks that function.

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

This component belongs to the AP7354 series of ultra-low quiescent current LDOs from Diodes Incorporated. The series provides various fixed output voltages ranging from 1.1V to 4.5V. The AP7354-15FS4-7 specifically denotes the 1.5V output version housed in the X2-DFN1010-4 package without an integrated output discharge resistor, distinguishing it from the AP7354D variants.
