TPS7A2042PDQNR TI LDO Regulator | 4-X2SON(1x1) | 200mA, 1.2V to 6.5V

Product Overview

The TPS7A2042PDQNR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for space-constrained applications. It offers a compact 4-pin X2SON package (1 mm x 1 mm) and delivers up to 200 mA output current with a dropout voltage as low as 150 mV at full load. The device operates over an input voltage range of 1.2 V to 6.5 V and provides a fixed output voltage of 4.2 V with ±1% accuracy. Its low quiescent current (typical 1 µA) makes it ideal for battery-powered devices.
