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

Product Overview

The LP2985-18DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver 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 ideal for space-constrained applications requiring low noise and high accuracy. Its low dropout voltage (typically 300mV at 150mA) ensures efficient operation even when the input voltage is close to the output. The LP2985-18DBVR features a shutdown mode that reduces quiescent current to less than 1µA, making it suitable for battery-powered devices. With built-in overcurrent and thermal protection, it provides reliable performance in demanding environments.
