TPS7A0222DQNR TI LDO Regulator | 4-X2SON(1x1) | 2.2V Fixed Output, 200mA

Product Overview

The TPS7A0222DQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It offers a fixed output voltage of 2.2V with a maximum output current of 200mA. Housed in a compact 4-pin X2SON (1mm x 1mm) package, this device provides excellent line and load transient response while maintaining low quiescent current. The TPS7A02 family is optimized for battery-powered and noise-sensitive systems, delivering high PSRR and low output noise.
