TLV74333PDQNR TI LDO Regulator | 4-X2SON(1x1) | 3.3V Output, 300mA

Product Overview

The TLV74333PDQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering a fixed output voltage of 3.3V with a maximum output current of 300mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), it is designed for space-constrained applications requiring high efficiency and low noise. The device features a low dropout voltage of typically 150mV at full load, enabling operation from input voltages as low as 3.48V. With a quiescent current of only 25µA (typical), it is ideal for battery-powered devices. The TLV74333PDQNR also includes overcurrent protection and thermal shutdown for robust operation.
