LP2985-18DBVRM3 TI LDO Regulator | SOT-23-5 | 1.8V Output, 150mA

Product Overview

The LP2985-18DBVRM3 is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 150mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). Its low dropout voltage of typically 300mV at full load ensures efficient operation even when the input voltage is close to the output. The LP2985-18DBVRM3 also features a shutdown mode that reduces quiescent current to less than 1µA, making it suitable for battery-powered devices.
