Overview
The AN7706SP is a 3-pin positive output low dropout voltage regulator with a fixed 6 V output and 1.2 A current capability. It features a minimum input-output voltage difference of 0.5 V typical. The recommended operating supply voltage range is 7 V to 17 V. Electrical characteristics include a line regulation of 60 mV maximum and load regulation of 120 mV maximum at 500 mA. The device incorporates on-chip overcurrent limiting, thermal protection, inrush current protection, and input short-circuit protection circuits.
Feature Summary
- Integrated overcurrent limiter for load protection
- Built-in thermal protection circuit to prevent overheating
- Input short-circuit protection prevents reverse current flow
- Inrush current protection during input voltage start-up
Applications
- Power supply equipment
- Low-voltage battery-driven equipment
- Home appliances
- Industrial equipment with fluctuating supply voltages
Procurement Notes
Verify the specific package type (SP-3SU or lead-free SP-3SUA) as dimensions differ slightly. Confirm the manufacturer's current product status, as older series may be discontinued. Ensure the application environment stays within the specified -30°C to +85°C operating temperature range. Check for any required external compensation capacitors to maintain stability under varying load conditions.
Selection Notes
Select this component when a stable 6 V rail is required from an input voltage between 7 V and 17 V. It is suitable for designs needing high peak currents up to 2.4 A temporarily. Consider the thermal resistance derating curves if operating near maximum power dissipation. Verify that the output capacitor ESR remains within the recommended area to prevent oscillation.
Part Context
This part belongs to the AN77xxSP series of 3-pin positive LDO regulators. The series offers various fixed output voltages ranging from 3.3 V to 15 V. All variants share similar internal protection structures and package options. The series is designed for applications requiring small input-output voltage differentials and robust protection against electrical faults.
Replacement Considerations
Consult Panasonic Industry for official cross-reference data. Verify pin compatibility and thermal performance before substituting. Ensure the replacement supports the same 1.2 A output current and 6 V fixed output requirement.
