TPS78417QDBVRQ1 TI LDO Regulator | SOT-23-5 | 1.7V Output, 400mA

Product Overview

The TPS78417QDBVRQ1 from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for automotive and industrial applications. It offers a fixed output voltage of 1.7V with a maximum output current of 400mA. The device is housed in a compact SOT-23-5 package, making it suitable for space-constrained designs. With a typical dropout voltage of only 200mV at full load, it ensures efficient power conversion even when the input voltage is close to the output. The TPS78417QDBVRQ1 features high accuracy, low quiescent current, and robust protection features including overcurrent and overtemperature shutdown.
