TLV73333PQDBVRQ1 TI LDO Regulator | SOT-23-5 | 3.3V Output, 300mA

Product Overview

The TLV73333PQDBVRQ1 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive applications. It provides a fixed output voltage of 3.3V with a maximum output current of 300mA. The device is housed in a compact SOT-23-5 package, making it suitable for space-constrained designs. With a low dropout voltage of typically 200mV at full load, it ensures efficient regulation even when the input voltage is close to the output. The TLV73333PQDBVRQ1 features a wide input voltage range from 1.7V to 5.5V, enabling use in various automotive power rails. It also includes built-in protection features such as overcurrent protection and thermal shutdown, enhancing system reliability.
