Overview
The AN77L035M is a 3-pin, fixed positive output monolithic voltage regulator from Panasonic Industry. It provides a stable 3.5 V output with a maximum current capacity of 100 mA. The device operates within a supply voltage range of (VOUT + 0.41 V) to 14.14 V and requires a 10 μF output capacitor for stabilization. It features a minimum input/output voltage difference of 0.22 V typical at full load. The component utilizes a 3-HSIP package and includes internal protection mechanisms against overcurrent, overheating, and input short circuits.
Feature Summary
- Integrated overcurrent limit circuit to protect against excessive load currents.
- Built-in rush current prevention circuit to manage input voltage rise conditions.
- Overheat protection circuit that cuts off output when junction temperature exceeds limits.
- Input short-circuit protection circuit prevents element damage during fault conditions.
Applications
- Power supply circuits for low-voltage battery-operated equipment
- Consumer electronic devices requiring stable fixed voltage regulation
- Industrial equipment subject to significant supply voltage fluctuations
Procurement Notes
Verify the specific lifecycle status as this product may be discontinued or under maintenance. Confirm package availability and lead times through authorized distributors. Ensure compatibility with existing PCB footprints and thermal management requirements. Check for updated datasheets to confirm electrical characteristics match design specifications.
Selection Notes
Select this regulator for applications requiring a fixed 3.5 V output up to 100 mA. Consider the 0.22 V typical dropout voltage for efficiency in low-voltage systems. Ensure the input voltage remains within the specified operating range. Verify thermal dissipation capabilities based on ambient temperature and load conditions.
Part Context
The AN77L035M belongs to the AN77LxxM series of 3-pin positive output low dropout voltage regulators. This series offers multiple fixed output voltages ranging from 3 V to 12 V. All variants share similar internal architectures and protection features, differing primarily in their regulated output voltage levels.
Replacement Considerations
Public confirmed substitute part numbers include L78L33ACUTR and MIC5200-3.3YS. Verify pinout compatibility and electrical parameters before substitution.
FAQ
Is an external protection diode required for input short-circuit conditions?
No, the AN77L035M incorporates an internal input short-circuit protection circuit, eliminating the need for an external silicon diode typically used in conventional regulators.
What type of output capacitor is recommended for stability?
A 10 μF capacitor is required. Tantalum capacitors or aluminum electrolytic capacitors with equivalent series resistance within the recommended range are advised to prevent oscillation, especially at low temperatures.
