Overview
The AN77L03 is a 3-pin, fixed positive output monolithic voltage regulator from the Panasonic AN77Lxx series. It provides a stable 3 V DC output with a maximum current capacity of 100 mA. The device operates within an input supply voltage range of (VOUT + 0.3 V) to 13.62 V. It features a minimum input/output voltage difference of 0.18 V typical at 100 mA load. The component utilizes a silicon monolithic bipolar IC structure housed in an SSIP003-P-0000S package.
Feature Summary
- Built-in overcurrent limit circuit for protection against excessive load currents
- Integrated rush current prevention mechanism during input voltage rise
- Overheat protection circuit that cuts off output when internal temperature exceeds limits
- Input short-circuit protection circuit incorporated internally
Applications
- Power supply circuits requiring up to 100 mA current capacity
- Low-voltage equipment utilizing batteries
- Consumer and industrial equipment with significant supply voltage fluctuations
Procurement Notes
Verify the specific lifecycle stage before procurement as the AN77L03 falls under Maintenance/Discontinued categories. Confirm the package code SSIP003-P-0000S matches design requirements. Review the latest product standards directly from Panasonic Semiconductor Solutions to ensure specifications remain valid for the intended application timeline.
Selection Notes
Select this regulator for applications needing a fixed 3 V output with moderate current demands. Ensure the input voltage remains within the specified operating range. Designers must include a 10 μF output capacitor near the pins to secure stability. Verify thermal dissipation limits against ambient temperature conditions to prevent overheating.
Part Context
This component belongs to the AN77Lxx series of 3-pin positive output low dropout voltage regulators. The series offers multiple fixed output voltage options including 3 V, 3.5 V, 4 V, 4.5 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, and 12 V. All variants share similar structural characteristics and protection features.
Replacement Considerations
Consult official Panasonic documentation for verified substitute part numbers within the AN77Lxx series or equivalent legacy components. Cross-reference pinouts and electrical characteristics carefully.
