LP2985A-18DBVR TI LDO Regulator | SOT-23-5 | 1.8V Output, 150mA

Product Overview

The LP2985A-18DBVR is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed output voltage of 1.8V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). It features a dropout voltage of only 300mV at full load, enabling efficient operation even with minimal input-to-output voltage differential. The LP2985A-18DBVR is ideal for powering sensitive analog and digital circuits in portable and industrial equipment.
