TPS7A0518PDQNR TI LDO Regulator | 4-X2SON(1x1) | 1.8V Fixed Output, 200mA

Product Overview

The TPS7A0518PDQNR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It offers a fixed output voltage of 1.8V with a maximum output current of 200mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), this device provides excellent line and load transient response while maintaining low quiescent current. The TPS7A05 series is optimized for battery-powered and portable electronics where power efficiency and small footprint are critical.
