Overview
The ADP5138ACPZ-2-R7 is a specialized Power Management IC (PMIC) from Analog Devices, featuring a qualified buck converter and an additional regulator. It operates within an input voltage range of 1.7 V to 5.5 V and supports output voltages from 1 V to 3.3 V. The device provides output currents of 250 mA and 1 A across its channels. Packaged in a 28-pin LFCSP for surface mount installation, it functions reliably between -40°C and +125°C with a quiescent current of 6 mA.
Feature Summary
- Integrates a qualified buck converter alongside an additional regulator within a single PMIC solution
- Supports wide input voltage ranges suitable for battery-powered applications
- Designed for high thermal performance with extended industrial temperature ratings
Applications
- Portable electronic devices requiring efficient power management
- Industrial control systems operating in extreme temperatures
- Battery-powered equipment needing compact power solutions
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.
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.
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.
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.
