LP3990TL-2.5/NOPB TI LDO Regulator | 4-DSBGA (1x1) | 2.5V Output, 150mA

Product Overview

The LP3990TL-2.5/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 2.5V with a maximum output current of 150mA. Housed in a compact 4-DSBGA (1x1 mm) package, it is designed for space-constrained applications requiring high performance and low noise. The device features a low dropout voltage of typically 120mV at 150mA load, enabling efficient operation even with small input-to-output voltage differentials. With a quiescent current of only 25µA (typical), it is ideal for battery-powered devices. The LP3990TL-2.5/NOPB also includes overcurrent and thermal shutdown protection, ensuring reliable operation under fault conditions.
