TPS79401DCQR TI LDO Regulator | SOT-223-6 | 3.0V Output, 250mA

Product Overview

The TPS79401DCQR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 3.0V output with up to 250mA of load current. Housed in a compact SOT-223-6 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive analog and digital circuits. With a dropout voltage of only 170mV at full load, it efficiently regulates from input voltages as low as 3.17V. The TPS79401DCQR integrates a shutdown feature for power savings and includes overcurrent and thermal protection.
