TPS7A20L12PDQNR TI LDO Regulator | 4-X2SON(1x1) | 1.2V Fixed Output, 300mA

Product Overview

The TPS7A20L12PDQNR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.2V with a maximum output current of 300mA. Housed in a compact 4-pin X2SON package (1mm x 1mm), it is designed for space-constrained applications requiring high efficiency and low noise. The device features a low dropout voltage of typically 120mV at full load, enabling operation with minimal headroom. With an ultra-low quiescent current of 1µA (typical) and a shutdown current of 0.1µA, it is ideal for battery-powered and portable electronics. The TPS7A20L12PDQNR also includes overcurrent and overtemperature protection, ensuring reliable performance in demanding environments.
