LF50CDT

Overview

The LF50CDT-TR is a low-dropout linear voltage regulator from the LFXX series, manufactured by STMicroelectronics. It provides a fixed positive output voltage of 5V with a maximum output current of 500mA. The device features a very low dropout voltage of approximately 0.45V to 0.7V at full load and a typical quiescent current of 1mA. It operates within an input voltage range up to 16V and supports junction temperatures from -40°C to +125°C. Packaged in a TO-252-3 (DPAK) surface-mount case, it includes internal protection against overcurrent and thermal overload.

Feature Summary

Very low dropout voltage enables efficient operation with minimal input-output differential.
Low quiescent current consumption optimizes power efficiency for battery-powered applications.
Integrated thermal overload and short-circuit current limiting protect the device under fault conditions.

Applications

Battery-powered systems requiring low noise and high efficiency
Multi-output power supplies with sequence control requirements
General-purpose linear regulation in portable electronic devices

Procurement Notes

Verify the specific suffix (e.g., TR for tape and reel) matches your assembly needs. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) for your manufacturing process. Ensure the DPAK package footprint aligns with your PCB design guidelines. Cross-reference datasheet revisions for any parameter updates before finalizing procurement.

Selection Notes

Select this component when a fixed 5V output is required with moderate current capability up to 500mA. Consider the thermal performance in the DPAK package for your expected load and ambient temperature. Verify that the input voltage remains within the 16V maximum limit while maintaining sufficient headroom for the specified dropout voltage during operation.

Part Context

This part belongs to the LFXX family of ultra-low-dropout regulators designed for low-noise, low-power applications. The LF50 variant specifically offers a fixed 5V output. The 'CDT' designation indicates the TO-252-3 (DPAK) surface-mount package, suitable for automated assembly processes in compact electronic designs.
