TPS76930QDBVRG4Q1 TI LDO Regulator | SOT-23-5 | 3.0V Output, 100mA

Product Overview

The TPS76930QDBVRG4Q1 from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for automotive and industrial applications. It provides a fixed output voltage of 3.0V with a maximum output current of 100mA. The device is housed in a compact SOT-23-5 package, making it ideal for space-constrained designs. With a low dropout voltage of typically 71mV at 100mA load, it ensures efficient operation even when the input voltage is close to the output. The TPS76930QDBVRG4Q1 features a quiescent current of 17µA (typical) and offers excellent line and load regulation. It includes built-in protection features such as overcurrent limiting and thermal shutdown, enhancing system reliability.
