Overview
The AN79L12 is a fixed negative output monolithic voltage regulator from the AN79Lxx series, manufactured by Panasonic. It provides a stabilized -12V DC output with a maximum current capacity of 100mA. The device operates without external components for basic regulation and features built-in overcurrent limiting and thermal overload protection circuits. It accepts unstable DC input voltages to produce a regulated negative supply.
Feature Summary
- Integrated overcurrent limit circuit
- Built-in thermal overload protection circuit
- Fixed negative output voltage type
Applications
- Power circuits requiring up to 100mA current capacity
- Negative voltage generation from unstable DC inputs
- Standard electronic equipment power supplies
Procurement Notes
Verify the specific package variant (AN79L12 or AN79L12M) against the required lead-free designation (SSIP003-P-0000S or HSIP003-P-0000Q). Confirm that the application environment remains within standard operating temperature ranges, as special applications like aerospace or life support systems require separate consultation with sales staff.
Selection Notes
Select this component when a fixed -12V negative rail is needed for low-current applications up to 100mA. Ensure the input voltage range accommodates the minimum dropout requirements specified in the datasheet. Consider the thermal dissipation characteristics if operating at higher ambient temperatures or near maximum load currents.
Part Context
This part belongs to the AN79Lxx/AN79LxxM series of 3-pin negative output voltage regulators. The series includes twelve types of output voltages ranging from -4V to -24V. The AN79L12 specifically targets the -12V requirement within this family of monolithic regulators designed for general-purpose power circuit stabilization.
Replacement Considerations
Datasheet notes indicate package transitions to lead-free types SSIP003-P-0000S and HSIP003-P-0000Q. Verify pinout compatibility if substituting between the original and new package specifications.
