TPS7A0318DQNR TI LDO Regulator | 4-X2SON(1x1) | 300mA, 1.8V Output

Product Overview

The TPS7A0318DQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It delivers up to 300 mA output current with a fixed output voltage of 1.8 V. The device operates from an input voltage range of 1.4 V to 5.5 V, making it suitable for battery-powered and low-voltage systems. Housed in a compact 4-pin X2SON (1 mm x 1 mm) package, it offers excellent thermal performance and minimal footprint.
