TPS71519DCKR TI LDO Regulator | SC-70-5 | 1.9V Output, 50mA

Product Overview

The TPS71519DCKR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for low-power applications. It provides a fixed output voltage of 1.9V with a maximum output current of 50mA. The device features a low dropout voltage of typically 330mV at full load and a quiescent current of only 3.2µA, making it ideal for battery-powered and portable electronics. Housed in a compact SC-70-5 package, the TPS71519DCKR offers excellent line and load regulation, ensuring stable performance across varying input voltages and load conditions.
