Overview
The AN78L12 is a three-terminal positive output voltage regulator from the AN78Lxx series, manufactured by Panasonic Electronic Components. It provides a fixed 12 V output with a maximum current capacity of 100 mA. The device operates within an input voltage range of 14.5 V to 27 V and features built-in overcurrent limit and thermal overload protection circuits. It utilizes a silicon monolithic bipolar IC technology housed in a SSIP003-P-0000S package.
Feature Summary
- Fixed 12 V output voltage
- Built-in overcurrent limit circuit
- Built-in thermal overload protection circuit
Applications
- Power circuits requiring up to 100 mA current capacity
- Obtaining stabilized fixed output voltage from unstable DC input sources
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package code SSIP003-P-0000S matches design requirements. Review the latest product standards for any specification updates before finalizing procurement decisions.
Selection Notes
Select this component when a stable 12 V supply is needed for low-power applications up to 100 mA. Ensure the input voltage remains between 14.5 V and 27 V. Consider the thermal dissipation limits relative to ambient temperature during operation.
Part Context
This part belongs to the AN78Lxx series of three-pin positive output voltage regulators. The series includes various fixed output voltages such as 4 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V, and 24 V. All variants share similar internal protection mechanisms and packaging.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-reference electrical characteristics and pin configurations carefully before implementation.
