Voltage Regulators - Linear + Switching Procurement Notes

Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the ACPZ designation matches your required lead-free and RoHS compliance standards. Ensure the -2 variant aligns with your circuit design requirements regarding internal configuration. Cross-reference the datasheet for any recent updates to the qualification status of the integrated buck converter before finalizing procurement.

Voltage Regulators - Linear + Switching Selection Notes

Select this component when a qualified buck converter is mandatory for safety-critical or regulated environments. Compare the 250 mA and 1 A output capabilities against your load requirements. Consider the LFCSP-28 package size constraints relative to your PCB layout. Evaluate the 1.7 V minimum input voltage against your lowest expected supply rail to ensure proper regulation under all conditions.

Voltage Regulators - Linear + Switching Part Context

This part belongs to the ADP5138 series of professional power management ICs. It is distinct from other ADP5xxx regulators by combining a qualified switching regulator with linear regulation. The product line targets applications demanding high reliability and compact form factors in harsh environments.

Voltage Regulators - Linear + Switching Replacement Considerations

Check for ADP5138ACPZ-1-R7 if only the 250 mA channel is required. Verify compatibility with ADP5134 for similar buck topologies without qualification requirements.
