LF50CDT-TR ST LDO Regulator | DPAK | 5V Output, 500mA

Product Overview

The LF50CDT-TR is a low-dropout voltage regulator from STMicroelectronics, offering a fixed output voltage of 5V with a maximum output current of 500mA. Housed in a DPAK (TO-252) surface-mount package, it is designed for applications requiring a stable and efficient power supply with minimal dropout voltage. The device features a very low dropout voltage (typically 0.4V at 500mA), making it suitable for battery-powered systems and post-regulation stages. It includes internal current limit and thermal shutdown protection, ensuring reliable operation under fault conditions.
