LP3985ITL-2.8/NOPB TI LDO Regulator | 5-DSBGA (1.41x1.08) | 2.8V Output, 150mA

Product Overview

The LP3985ITL-2.8/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 2.8V with a maximum output current of 150mA. Housed in a compact 5-DSBGA (1.41x1.08mm) 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 120mV at full 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.
