Overview
The AN78M05NSP is a monolithic positive voltage regulator from the AN78MxxNSP series, housed in an SP-3SU surface-mount package. It provides a fixed output of 5 V with a maximum current capacity of 500 mA. The device operates within an ambient temperature range of -30°C to +85°C and supports a supply voltage up to 35 V. Electrical characteristics include a line regulation of 100 mV (VI=7.5 V to 25 V) and a load regulation of 100 mV (IO=5 mA to 500 mA). Minimum external components required are CI ≥ 0.33 µF and CO ≥ 0.1 µF.
Feature Summary

- Built-in thermal overload protection circuit
- Built-in ASO (area of safe operation) protection circuit
Applications
- Power circuits requiring stabilized fixed output voltage
- General electronic equipment
- Office equipment
- Communications equipment
- Measuring instruments
Procurement Notes
Verify the latest specifications directly with Panasonic Industry sales representatives before initiating mass production or purchasing. Product specifications, manufacturing locations, and availability are subject to change without notice. Confirm that the datasheet version matches the specific lot requirements for your application design.
Selection Notes
Ensure the input voltage remains within the 35 V absolute maximum rating and consider derating power dissipation based on the specific PCB mounting conditions. Verify that the required output current does not exceed 500 mA. Check if the lead-free SP-3SUA package variant is acceptable for the assembly process.
Part Context
This component belongs to the AN78MxxNSP series, which includes nine variants offering fixed output voltages ranging from 5 V to 18 V. All members share identical pinouts, package dimensions, and internal protection features, differing only in their regulated output voltage levels.
Replacement Considerations
The datasheet notes a package transition to the lead-free SP-3SUA type. No alternative part numbers are listed as direct substitutes.
FAQ
Is this component suitable for automotive electronics?
No, the datasheet explicitly states that this IC is not suitable for car electronics equipment.
What happens if the junction temperature exceeds 150°C?
The internal thermal protection circuit cuts off the output when the junction temperature exceeds 150°C.
