LP5990TM-1.8/NOPB TI Linear Voltage Regulator | 4-DSBGA | 1.8V Output, 200mA

Product Overview

The LP5990TM-1.8/NOPB is a low-dropout linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.8V with a maximum output current of 200mA. Housed in a compact 4-DSBGA package, it is designed for space-constrained applications requiring high efficiency and low noise. The device features a low dropout voltage of typically 120mV at full load, enabling operation from input voltages as low as 2.0V. With a quiescent current of only 30µA, it is ideal for battery-powered systems. The LP5990TM-1.8/NOPB also includes overcurrent and thermal shutdown protection, ensuring reliable operation under fault conditions.
