TLV73330PDQNT TI LDO Regulator | 4-X2SON(1x1) | 3.3V Output, 300mA

Product Overview

The TLV73330PDQNT is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 3.3V with a maximum output current of 300mA. Housed in a compact 4-pin X2SON (1mm x 1mm) package, it is designed for space-constrained applications requiring high efficiency and low noise. The device features a low dropout voltage of typically 230mV at full load, enabling operation with minimal headroom. With a quiescent current of only 34μA, it is ideal for battery-powered systems. The TLV73330PDQNT also includes overcurrent protection and thermal shutdown for robust performance.
