Overview
The L78LR05E-FA-E is a fixed positive standard linear voltage regulator manufactured by Sanyo. It provides a nominal output voltage of 5 V with a tolerance range of 4.75 V to 5.25 V. The device supports a maximum output current of 150 mA and operates within an input voltage range of 7 V to 20 V. It features integrated reset functionality for system protection. The component is housed in a 4-pin small outline package (SOP) with gull-wing terminals, suitable for surface mount applications.
Feature Summary
- Integrated reset function for enhanced system reliability
- Fixed 5V output with tight voltage tolerance
- Surface mount compatible small outline package
Applications
- Embedded systems requiring stable 5V logic supply
- Microcontroller power management circuits
- Industrial control modules with reset requirements
Procurement Notes
Verify the specific suffix 'FA-E' against the manufacturer's official documentation to confirm pinout and thermal characteristics. Ensure the source document explicitly lists this part number as active or available. Cross-reference the 4-pin SOP package dimensions with your PCB footprint design. Confirm RoHS compliance status directly from the latest datasheet revision provided by Sanyo Semiconductor.
Selection Notes
Select this component when a fixed 5V output with integrated reset capability is required in a compact surface mount form factor. The 150 mA current limit suits low-power digital loads. Verify that the input voltage remains within the 7V to 20V operational window. Consider thermal dissipation requirements for the plastic epoxy package under maximum load conditions.
Part Context
This part belongs to the L78LR series of voltage regulators with reset functions produced by Sanyo. The series offers fixed output voltages with built-in supervision features. The L78LR05E-FA-E specifically denotes the 5V variant in a 4-pin surface mount configuration. It is designed for applications needing reliable power sequencing and voltage monitoring in space-constrained designs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Sanyo's official replacement guide or contact the manufacturer directly for qualified alternatives.
