Overview
The LF50CV-DG is a very low drop voltage regulator from the LFXX series, designed for low-noise and low-power applications. It provides a fixed 5 V output with a maximum output current of 0.5 A. The device operates within an input voltage range of -0.5 V to 40 V and features a typical dropout voltage of 0.45 V. Packaged in a 3-Pin (3+Tab) TO-220AB tube, it includes basic inhibit functions suitable for battery-powered systems.
Feature Summary
- Very low dropout voltage operation
- Low quiescent current consumption
- Basic inhibit functionality
Applications
- Battery powered systems
- Low noise applications
- Low power applications
Procurement Notes
Verify the specific suffix 'DG' against official STMicroelectronics documentation to confirm package type and availability status. Ensure the ordering code matches the required TO-220AB configuration. Confirm that the basic inhibit function meets system requirements before procurement.
Selection Notes
Select this component for designs requiring a fixed 5 V rail with minimal voltage loss. The 0.5 A current capability suits moderate load applications. Verify thermal management needs for the TO-220AB package under expected load conditions.
Part Context
This part belongs to the LFXX family of very low drop regulators. The series offers various output voltages optimized for low-noise environments. The LF50CV variant specifically targets 5 V regulation with integrated inhibit control.
Replacement Considerations
Check for direct substitutes within the LFXX series offering identical 5 V output and 0.5 A current rating. Verify pin compatibility and thermal performance for equivalent packages.
