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

Verify the specific ordering suffix FS4 confirms the X2-DFN1010-4 (Type B) package type. Confirm that the absence of 'D' in the part number indicates the non-discharge version, as discharge functionality is only available in SOT25 and X2-DFN packages with the 'D' suffix. Ensure compatibility with RoHS 3 and halogen-free requirements if mandated by your supply chain standards.

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

Select this component when a compact footprint is required alongside high voltage accuracy. The X2-DFN1010-4 package offers a small surface area suitable for space-constrained designs. Note that the enable pin is not present on SOT23 variants, so verify package availability matches system control requirements. Ensure input voltage remains above the dropout threshold for the desired load current.

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

This part belongs to the AP7354 family of 150mA LDOs designed for low-power handheld and wearable devices. The series includes various output voltages and package options including SOT23, SOT25, and X2-DFN1010-4. The AP7354-12FS4-7 specifically denotes the 1.2V fixed output variant in the smallest DFN package without output discharge capability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

AP7354D-12FS4-7 serves as a direct substitute if output discharge functionality is required in the same package. Other AP7354 variants with different output voltages or packages may replace this unit if electrical parameters align with the design requirements.
