TPS78918DBVT TI LDO Regulator | SOT-23-5 | 1.8V Output, 100mA

Product Overview

The TPS78918DBVT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It provides a fixed output voltage of 1.8V with a maximum output current of 100mA. The device is housed in a compact SOT-23-5 package, making it ideal for portable and battery-powered electronics. With a low dropout voltage of typically 120mV at 100mA load, it ensures efficient operation even when the input voltage is close to the output. The TPS78918DBVT features a low quiescent current of 17µA, which extends battery life in standby modes. It also includes overcurrent and thermal shutdown protection for reliable operation.
