LP2985A-33DBVR TI LDO Regulator | SOT-23-5 | 3.3V Output, 150mA

Product Overview

The LP2985A-33DBVR is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It provides a fixed output voltage of 3.3V 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). The LP2985A-33DBVR features a low dropout voltage of typically 300mV at full load, making it ideal for battery-powered systems. Its ultra-low quiescent current (1.2mA typical) and shutdown mode (0.01µA typical) extend battery life in portable electronics.
