Overview
The AN77L09M is a 3-pin, fixed positive output monolithic voltage regulator from the Panasonic AN77Lxx series. It provides a stabilized 9 V output with a maximum current capacity of 100 mA. The device operates within a supply voltage range of (VOUT + 0.53 V) to 19.86 V and requires a 10 μF output capacitor for stability. It features a typical minimum input/output voltage difference of 0.28 V at full load.
Feature Summary
- Built-in overcurrent 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 requiring up to 100 mA
- Low-voltage equipment using batteries
- Consumer and industrial equipment with fluctuating supply voltages
Procurement Notes
Verify component status as the AN77Lxx series may be subject to maintenance or discontinuation phases. Confirm package code SSIP003-P-0000S matches design requirements. Ensure external components meet specified ESR ranges for stability. Consult official sources for latest lifecycle information before finalizing procurement plans.
Selection Notes
Select this regulator for applications needing a fixed 9 V output with low dropout characteristics. Verify that the input voltage remains within the 19.86 V absolute maximum rating. Ensure thermal dissipation stays within limits defined by the PD-Ta diagram. Use tantalum or aluminum electrolytic capacitors with appropriate ESR for stable operation across temperature ranges.
Part Context
The AN77L09M belongs to the AN77Lxx series of 3-pin positive output regulators manufactured by Panasonic. These silicon monolithic bipolar ICs are designed for general-purpose power management in consumer and industrial electronics. The series offers multiple fixed voltage options ranging from 3 V to 12 V.

FAQ
Is an external protection diode required for input short-circuit conditions?
No, the AN77L09M incorporates an internal input short-circuit protection circuit, eliminating the need for an external diode.
What type of output capacitor is recommended for stability?
A 10 μF capacitor is required. Tantalum or aluminum electrolytic capacitors with equivalent series resistance within the recommended range should be used to prevent oscillation.
