TLV74311PDQNR TI LDO Regulator | 4-X2SON (1x1) | 3.3V Output, 300mA

Product Overview

The TLV74311PDQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It delivers 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), this device offers excellent line and load regulation, making it ideal for noise-sensitive circuits. The TLV74311PDQNR features a low quiescent current of 25µA (typical) and a dropout voltage of 150mV at 300mA, ensuring efficient operation even under low input voltage conditions.
