LP3985ITL-3.1/NOPB TI LDO Voltage Regulator | 5-DSBGA (1.41X1.08) | 3.1V Output, 150mA

Product Overview

The LP3985ITL-3.1/NOPB is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 3.1V with a maximum output current of 150mA. Housed in a compact 5-DSBGA (1.41mm x 1.08mm) package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP3985 features a low dropout voltage of typically 80mV at 150mA load, enabling efficient operation even when the input voltage is close to the output. It also includes thermal shutdown and current limit protection for enhanced reliability.
