AN78L05

Overview

The AN78L05 is a monolithic fixed positive linear voltage regulator from the AN78Lxx series, manufactured by Panasonic Electronic Components. It provides a stable 5V output with a maximum current capacity of 100mA. The device operates within an input voltage range of 7.5V to 20V and requires no external components for basic regulation. Key electrical parameters include a typical line regulation of 150mV and load regulation of 11mV at 25°C. It features built-in overcurrent limiting and thermal overload protection circuits.

Feature Summary

Fixed positive output voltage regulation without external components
Integrated overcurrent limit circuit for short-circuit protection
Built-in thermal overload protection circuit

Applications

Power supply circuits requiring up to 100mA current capacity
General electronic equipment power regulation
Office equipment and communications equipment power management

Procurement Notes

Verify the specific package variant (AN78L05 or AN78L05M) as they differ in operating temperature ranges. Confirm lead-free status if required, noting that package types SSIP003-P-0000S and HSIP003-P-0000Q are the designated lead-free replacements. Ensure input wiring length considerations are addressed during design to prevent oscillation.

Selection Notes

Select this component for applications requiring a simple, fixed 5V source with moderate current needs. Consider the thermal dissipation characteristics, as power dissipation decreases significantly as ambient temperature rises above 25°C. Verify that the input voltage remains within the specified limits to ensure proper regulation and avoid damage.

Part Context

This part belongs to the AN78Lxx/AN78LxxM series of 3-pin positive output voltage regulators. The series includes multiple fixed voltage options ranging from 4V to 24V. The AN78L05 specifically targets the 5V requirement within this family, sharing common internal protection mechanisms and structural designs across the series.
