Internal overcurrent protection
Thermal overload protection

Applications

Power supply modules
Battery chargers
Embedded systems

Procurement Notes

Verify the specific suffix 'R-E' against official datasheets to confirm pinout and packaging details. Confirm RoHS compliance status with the manufacturer as regulatory requirements may vary by region and production batch. Ensure the supplier provides valid traceability documentation for automotive or industrial applications if required.

Selection Notes

Select this component when a fixed 5V rail is needed with moderate current capability. Consider the TO-220-5H package for through-hole mounting and adequate heat dissipation. Verify that the input voltage does not exceed the maximum rating to prevent device damage.

Part Context

This part belongs to the L78MR series of linear regulators. It is designed for general-purpose voltage regulation tasks where simplicity and reliability are prioritized. The series offers robust protection features suitable for various electronic circuits.

Replacement Considerations

Check for direct pin-compatible alternatives such as the L78MR05T-E or other manufacturers' equivalents like LM7805 variants, ensuring electrical parameters match.
