REG1117A-1.8 TI LDO Regulator | SOT-223-4 | 1.8V Fixed Output, 1A

Product Overview

The REG1117A-1.8 from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed to deliver a fixed 1.8V output with a maximum output current of 1A. Housed in a compact SOT-223-4 package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. With a dropout voltage of typically 1.1V at full load, it ensures stable operation even when the input voltage is close to the output. The REG1117A-1.8 integrates current limiting and thermal shutdown protection, enhancing system reliability.
