Overview
The AN7707SP is a three-pin, positive output, low dropout voltage regulator from the AN77xxSP series. It provides a fixed 7 V output with a maximum continuous current of 1.2 A. The device operates within an input supply voltage range of 8 V to 18 V and features a typical minimum input-to-output voltage difference of 0.5 V. It utilizes a SP-3SUA surface mount package.
Feature Summary
- Integrated on-chip overcurrent limiter for load protection
- Built-in thermal protection circuit to prevent overheating
- Input short-circuit protection circuit prevents reverse current flow when the input pin is grounded
- Inrush current protection circuit manages startup conditions
Applications
- Power supply equipment
- Low-voltage battery-driven equipment
- Home appliances
- Industrial equipment with significant supply voltage fluctuations
Procurement Notes
Verify the specific product lifecycle stage before procurement, as this component may be subject to maintenance or discontinuation plans. Confirm that the SP-3SUA package matches your board layout requirements. Ensure compliance with Panasonic Industry's warranty terms and check for any updates to the datasheet specifications prior to finalizing orders.
Selection Notes
Select this regulator for applications requiring a stable 7 V output up to 1.2 A. It is suitable for designs where the input voltage fluctuates significantly. Ensure the design accommodates the required external capacitors (0.33 μF input, 33 μF output) for stability. Verify that the operating temperature range meets the system's environmental demands.
Part Context
This component belongs to the AN77xxSP series of low dropout voltage regulators manufactured by Panasonic Industry. The series offers various fixed output voltages including 3.3 V, 5 V, 9 V, and 12 V. The AN7707SP specifically denotes the 7 V variant within this lineup of silicon monolithic bipolar ICs designed for surface mount applications.
Replacement Considerations
Consult Panasonic Industry's official cross-reference tools for verified substitute part numbers. Do not assume functional equivalence with other manufacturers' regulators without verifying pinouts, electrical characteristics, and thermal performance against the original datasheet.
