Overview
The TPS76350DBVR is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is part of the TPS763xx family, which offers low-dropout voltage, low-power operation, and miniaturized packaging. The TPS76350DBVR is specifically designed to provide a fixed output voltage of 5V with a maximum output current of 150mA. It is ideal for cost-sensitive designs and applications where board space is limited, such as in portable systems like laptops and cellular phones. The regulator features a PMOS pass element, which reduces dropout voltage and quiescent current compared to conventional LDO regulators.
