Overview
The AN78L05ME1 is a 3-pin, fixed positive output monolithic voltage regulator from the Panasonic AN78LxxM series. It provides a stabilized 5 V DC output from an unstable input source without requiring external components. The device supports a maximum current capacity of 100 mA and operates within a supply voltage range of 7.5 V to 20 V. It utilizes a silicon monolithic bipolar IC structure housed in a 3-pin plastic single inline package with a 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.
- Fixed 5 V output capability designed for stable power regulation in low-current applications.
Applications
- General electronic equipment power circuits
- Office equipment power supplies
- Communications equipment regulation
- Measuring instrument power management
Procurement Notes
Verify the current lifecycle status on the official Panasonic Semiconductor website before procurement, as the product may be subject to maintenance or discontinuation schedules. Confirm that the HSIP003-P-0000Q package code matches your design requirements. Ensure compliance with export control laws if transferring technical data or products across borders.
Selection Notes
Select this component for standard applications requiring a simple, fixed 5 V regulation at up to 100 mA. It is suitable for general-purpose electronics where minimal external circuitry is desired. Do not use for aerospace, automotive, or life-support systems without explicit manufacturer approval due to reliability constraints.
Part Context
This part belongs to the AN78LxxM series of 3-pin positive output voltage regulators. The series includes various fixed voltage options ranging from 4 V to 24 V. The AN78L05ME1 specifically denotes the 5 V variant within this lineup, sharing common features like internal short-circuit protection and thermal shutdown mechanisms across the family.
Replacement Considerations
Consult the official Panasonic discontinued product list for confirmed substitute part numbers. Verify compatibility with existing PCB footprints and electrical specifications before transitioning to any alternative components.
FAQ
What is the minimum input/output voltage difference required?
The minimum input/output voltage difference is typically 1.7 V at a junction temperature of 25°C.
How does the device handle thermal stress?
The device includes a built-in thermal overload protection circuit that cuts off the output when the internal junction temperature exceeds 150°C.
Is external component usage mandatory?
No, the regulator is designed to provide stabilized fixed output voltage without using any external components.
