REG1117-5 TI LDO Regulator | SOT-223-4 | 5V Fixed Output, 800mA

Product Overview

The REG1117-5 from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering a fixed 5V output with a maximum output current of 800mA. Housed in a compact SOT-223-4 package, it is designed for applications requiring a stable and efficient power supply with minimal dropout voltage. The device features a typical dropout voltage of 1.1V at full load, making it suitable for systems where the input voltage is close to the output voltage. With built-in current limiting and thermal shutdown protection, the REG1117-5 ensures reliable operation in demanding environments.
