LP3987ITL-2.8/NOPB TI LDO Regulator | 5-DSBGA (1.41X1.08) | 2.8V Output, 300mA

Product Overview

The LP3987ITL-2.8/NOPB is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 2.8V output with a maximum output current of 300mA. Housed in a compact 5-DSBGA package (1.41mm x 1.08mm), this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP3987 features a low dropout voltage of typically 120mV at full load, enabling efficient operation even when the input voltage is close to the output. With an operating input voltage range from 2.5V to 6.5V, it supports a wide variety of power sources, including single-cell Li-Ion batteries. The device also includes thermal shutdown and current limit protection, ensuring reliable operation under fault conditions.
