AN77L03M

Overview

The AN77L03M is a 3-pin, fixed positive output monolithic voltage regulator from Panasonic's AN77LxxM series. It provides a stable 3 V output with a maximum current capacity of 100 mA. Designed for low-dropout operation, it requires a minimum input/output voltage difference of 0.18 V typical. The device operates within a supply voltage range up to 13.62 V and includes internal protection circuits for over-current, over-temperature, rush current prevention, and input short-circuit conditions. A 10 μF output capacitor is required for stability.

Feature Summary

Built-in over current limit circuit
Built-in rush current prevention circuit at input voltage rise
Built-in overheat protection circuit
Built-in input short-circuit protection circuit

Applications

Power supply circuits for low-voltage equipment using batteries
Consumer equipment with great fluctuation of the supply voltage
Industrial equipment requiring stabilized fixed output voltage

Procurement Notes

Verify the specific lifecycle status (planned maintenance, maintenance, planned discontinued, or discontinued) via Panasonic Semiconductor official channels before procurement. Confirm package code HSIP003-P-0000Q matches design requirements. Ensure external component selection, particularly the output capacitor type and ESR, adheres to the recommended ranges in the datasheet to prevent oscillation.

Selection Notes

Select this component when a fixed 3 V output is required with a maximum load current of 100 mA. It is suitable for applications where the input voltage may fluctuate significantly but remains above the dropout threshold. Consider the SIP package form factor and thermal dissipation limits relative to ambient temperature. Verify that the application does not require output-to-ground short-circuit protection, as this feature is absent.

Part Context

The AN77L03M belongs to the AN77LxxM series of 3-pin positive output low dropout voltage regulators. This series offers 11 fixed output voltage options ranging from 3 V to 12 V. All variants share similar internal architectures, including built-in protection circuits and low dropout characteristics, differing primarily in their regulated output voltage levels.
