TPS71918-12DRVR TI LDO Regulator | 6-WSON (2x2) | Dual Output 1.8V/1.2V, 200mA

Product Overview

The TPS71918-12DRVR is a dual-output, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides two independent regulated outputs: 1.8V and 1.2V, each capable of delivering up to 200mA of load current. Housed in a compact 6-pin WSON (2mm x 2mm) package, this device is ideal for space-constrained applications requiring low noise and high power-supply rejection ratio (PSRR). The TPS71918-12DRVR features a low dropout voltage of typically 130mV at full load, making it suitable for battery-powered systems. It also includes enable pins for each output, allowing independent power sequencing. With a wide input voltage range of 2.5V to 6.5V, it can be powered from a variety of sources, including single-cell Li-ion batteries and 3.3V or 5V rails.
