Overview
The AN7710SP is a three-pin positive output low dropout voltage regulator from the Panasonic AN77xxSP series, designed for stable constant-voltage power supplies with minimal input-to-output voltage difference. It delivers a nominal 10 V output and supports a maximum continuous output current of 1.2 A. The device operates within an ambient temperature range of -30°C to +85°C and accepts supply voltages between 11 V and 21 V. Key electrical characteristics include a typical line regulation of 10 mV and load regulation of 50 mV under standard test conditions.
Feature Summary
- Integrated on-chip overcurrent limiter protects against excessive load demands.
- Built-in thermal protection circuit shuts down the output when junction temperature exceeds safe limits.
- Input short-circuit protection circuit prevents reverse current flow when the input pin is grounded.
- Inrush current protection circuit manages startup conditions to ensure stable operation.
Applications
- Power supply equipment
- Low-voltage battery-driven equipment
- Home appliances
- Industrial equipment
Procurement Notes
Verify the specific package variant (SP-3SU or lead-free SP-3SUA) required for your assembly process. Confirm that the operating supply voltage remains within the 11 V to 21 V range for the AN7710SP model. Ensure external capacitors meet the recommended ESR specifications to maintain stability and prevent oscillation during operation.
Selection Notes
Select this component when a fixed 10 V regulated output is required with high current capability up to 1.2 A. It is suitable for applications experiencing significant supply voltage fluctuations due to its low dropout characteristic. Consider the thermal derating requirements based on the expected ambient temperature and PCB mounting conditions to ensure reliable performance.
Part Context
The AN7710SP belongs to the AN77xxSP series of three-pin positive low dropout regulators manufactured by Panasonic Electronic Components. This series offers various fixed output voltages ranging from 3.3 V to 15 V, all sharing similar internal protection features and physical packaging options for consistent design integration across different power supply architectures.
Replacement Considerations
Consult official documentation for direct substitutes. The lead-free package variant SP-3SUA serves as a material alternative to the standard SP-3SU package without changing functional parameters.
