Overview
The L78LR05H-FA-E is a fixed positive standard linear voltage regulator manufactured by Sanyo. It provides a nominal output voltage of 5 V with a tolerance range of 4.75 V to 5.25 V. The device supports a maximum output current of 150 mA and operates within an input voltage range of 7 V to 20 V. Packaged in a small outline plastic package with four gull-wing terminals, it integrates reset functionality for system protection.
Feature Summary
- Integrates voltage regulation with built-in reset function for enhanced system reliability
- Provides stable fixed positive output voltage suitable for sensitive digital circuits
- Designed for surface mount applications with compact small outline packaging
Applications
- Digital signal processor power supply systems
- Motor control circuitry requiring stable logic levels
- Embedded systems needing integrated reset generation
Procurement Notes
Verify the specific suffix FA-E against official Sanyo documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact pin configuration and thermal characteristics required for your PCB layout. Cross-reference datasheet revision dates to guarantee compatibility with current manufacturing standards.
Selection Notes
Select this component when a combined voltage regulation and reset signal is required in a single package. It is appropriate for designs where board space is limited and a 150 mA load capacity at 5 V is sufficient. Consider thermal dissipation requirements given the small outline package constraints under maximum load conditions.
Part Context
This regulator belongs to Sanyo's L78LR series, which combines standard linear regulation with additional safety features. Unlike basic regulators, this variant includes hardware reset logic, reducing the need for external microcontroller supervision components. It serves as a specialized power management solution for embedded applications.
Replacement Considerations
Direct substitutes may include other L78LR series variants with different output voltages or reset thresholds. Verify pinout compatibility before replacing. Generic L7805 equivalents lack the integrated reset feature and are not functionally equivalent.
