Overview
The AN78L12M is a 3-pin fixed positive output monolithic voltage regulator from the Panasonic AN78LxxM series. It provides a stabilized 12 V DC output from an unstable input source without requiring external components. The device supports a continuous current capacity of up to 100 mA and operates within a supply voltage range of 14.5 V to 27 V. It utilizes a silicon monolithic bipolar IC structure housed in a 3-pin plastic single inline package with heat sink (HSIP003-P-0000Q).
Feature Summary
- Built-in overcurrent limit circuit for protection against excessive load currents.
- Integrated thermal overload protection circuit that cuts off output if junction temperature exceeds safe limits.
- Requires no external components to achieve stabilized fixed output voltage.
Applications
- Power circuits requiring stable 12 V regulation with low current demands.
- General electronic equipment such as office machines and measuring instruments.
- Communications equipment power supplies.
Procurement Notes
Verify the specific lifecycle status, as the datasheet indicates maintenance or discontinuation stages. Confirm the package code HSIP003-P-0000Q matches design requirements. Ensure compliance with export control laws if applicable. Consult official sources for the most recent product standards before final purchasing decisions.
Selection Notes
Select this component for applications needing a simple, fixed 12 V regulator with 100 mA capability. Verify that the operating ambient temperature remains within -30°C to +80°C. Ensure the input voltage stays between 14.5 V and 27 V. Consider the thermal dissipation limits when designing the heat sink requirements for the SIP package.
Part Context
This part belongs to the AN78LxxM series of 3-pin positive output voltage regulators. The series includes twelve types offering fixed outputs ranging from 4 V to 24 V. The AN78L12M specifically targets the 12 V requirement within this lineup, sharing common features like built-in protection circuits and the same SIP package format.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Panasonic channels for compatible alternatives or updated product information regarding discontinued items.
