- Peripheral interface power regulation
Procurement Notes
Verify component authenticity and datasheet revision when sourcing this part. Confirm pinout compatibility with existing PCB footprints due to the specific TO-220-5H package variant. Check for any obsolescence notices or lifecycle changes from onsemi prior to finalizing design-in decisions. Ensure thermal management solutions align with the package's power dissipation characteristics under expected load conditions.
Selection Notes
Select this component when a fixed 5V output with integrated reset signaling is required in a linear regulation topology. Consider the TO-220-5H package for through-hole mounting applications needing robust heat dissipation. Evaluate input-output voltage differentials to ensure efficient operation within the 24V maximum limit. Compare against other L78MR variants if different output voltages or package styles are needed for the specific application constraints.
Part Context
This part is part of onsemi's L78MR series, which focuses on linear voltage regulators with additional system management features like reset generation. The series targets applications requiring reliable power sequencing and stable voltage rails in industrial and consumer electronics environments.
Replacement Considerations
Public sources indicate the L78MR05-FA-E is obsolete and no longer manufactured. Verify availability of direct substitutes or equivalent parts with matching 5V/0.5A specifications and TO-220-5H packages from authorized distributors.
