Overview
The AN78L07 is a 3-pin fixed positive output monolithic voltage regulator from the AN78Lxx series, manufactured by Panasonic Industry. It provides a stabilized 7V DC output with a maximum current capacity of 100mA without requiring external components. The device features built-in overcurrent limiting and thermal overload protection circuits to ensure operational safety. It accepts an unstable DC input voltage within a specified range and delivers a regulated output suitable for low-power electronic applications.
Feature Summary
- Provides a fixed 7V positive output voltage directly from an unstable DC input source
- Integrates internal overcurrent limit circuitry to protect against excessive load conditions
- Includes built-in thermal overload protection circuit to prevent damage during overheating
Applications
- Power supply circuits for general electronic equipment
- Voltage regulation in household appliances
- Powering low-current logic circuits and sensors
Procurement Notes
Verify component authenticity and datasheet revision status before integration. Confirm package type availability as legacy variants may have transitioned to lead-free specifications. Ensure design compliance with absolute maximum ratings regarding input voltage and power dissipation limits under expected operating temperatures.
Selection Notes
Select this regulator when a stable 7V supply is required for loads drawing up to 100mA. Consider the minimum input-output voltage difference requirement to maintain regulation. Evaluate thermal management needs based on the power dissipation characteristics and ambient temperature conditions of the target application environment.
Part Context
This component belongs to the AN78Lxx/AN78LxxM series of 3-pin positive voltage regulators. The series offers twelve fixed output voltage options ranging from 4V to 24V. All variants share similar architectural features, including internal protection mechanisms and the capability to operate without external adjustment components, providing a standardized solution for simple linear regulation tasks.
Replacement Considerations
Cross-reference with other manufacturers' 78L07 equivalents if Panasonic stock is unavailable. Verify pinout compatibility and electrical parameter alignment, specifically output voltage tolerance and current limits, before substituting.
