LP3988QMFX-2P85 TI LDO Regulator | SOT-23-5 | 2.85V Output, 150mA

Product Overview

The LP3988QMFX-2P85 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 2.85V with a maximum output current of 150mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained and power-sensitive applications. With a low dropout voltage of typically 120mV at 150mA load, the LP3988 ensures efficient operation even when the input voltage is close to the output. The device features a low quiescent current of 30µA (typical) and a shutdown mode that reduces current consumption to less than 1µA, extending battery life in portable devices.
