Product Overview
The LP3985ITL-2.9/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed output voltage of 2.9V with a maximum output current of 150mA. 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 LP3985 series offers excellent transient response and low quiescent current, making it suitable for battery-powered and portable electronics.
