Overview
The AN77L03M is a 3-pin, fixed positive output monolithic voltage regulator providing a nominal 3 V DC output with a maximum current capacity of 100 mA. It operates within an input supply voltage range from (VOUT + 0.3 V) to 13.62 V. The device features a typical minimum input/output voltage difference of 0.18 V at 100 mA load and includes built-in overcurrent limit, rush current prevention, overheat protection, and input short-circuit protection circuits.
Feature Summary
- Built-in overcurrent limit circuit for load protection
- Integrated rush current prevention circuit during input voltage rise
- Overheat protection circuit that cuts off output when junction temperature exceeds 150°C
- Internal input short-circuit protection eliminating the need for external diodes
Applications
- Power supply circuits for low-voltage battery-operated equipment
- Consumer electronic devices requiring stable fixed voltage regulation
- Industrial equipment experiencing significant supply voltage fluctuations
Procurement Notes
Verify component authenticity through authorized Panasonic Industry distributors or certified partners. Confirm package code HSIP003-P-0000Q matches physical markings. Review latest datasheet revisions as specifications may change without notice. Ensure compliance with export control regulations if applicable. Validate suitability for specific application requirements before mass production deployment.
Selection Notes
Select this regulator for applications requiring a fixed 3 V output up to 100 mA. Ensure input voltage remains within the specified operating range. Use a 10 μF output capacitor near pins 1 and 2 for stability. Consider thermal dissipation limits based on ambient temperature conditions. Verify compatibility with required equivalent series resistance ranges for output capacitors.
Part Context
The AN77L03M belongs to the AN77LxxM series of 3-pin plastic single inline packages with heat sink (SIP type). These silicon monolithic bipolar ICs offer fixed positive outputs in multiple 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 variants.
Replacement Considerations
Consult official Panasonic Industry documentation for verified substitute part numbers. Cross-reference pin configurations and electrical characteristics carefully. Ensure replacement components meet identical absolute maximum ratings and package dimensions.
