Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm availability status as distribution channels may list limited stock or special order requirements. Ensure compatibility with required PCB footprint dimensions and thermal management strategies before finalizing procurement decisions.
Selection Notes
Select this regulator for applications requiring high input voltages up to 40 V with low quiescent current consumption. Consider the LFCSP package for space-constrained designs needing excellent thermal performance. Verify that the application load current remains within the 200 mA limit and that appropriate ceramic capacitors are used to maintain stability.
Part Context
This component belongs to the ADP7142 series of low dropout regulators designed for high-performance analog and mixed-signal circuits. The series supports various fixed output voltages and adjustable configurations. It is AEC-Q100 qualified for automotive applications, indicating suitability for demanding environments requiring robust power management solutions.
Replacement Considerations
Consult official Analog Devices documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications when considering alternatives.
