LP5900TL-1.8/NOPB Description

The LP5900TL-1.8/NOPB is a high-performance, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 150mA. This regulator is optimized for applications requiring ultra-low noise, high power supply rejection ratio (PSRR), and minimal quiescent current. It operates over an input voltage range of 1.9V to 5.5V, making it suitable for battery-powered and noise-sensitive systems. The device is housed in a compact 4DSBGA package, ideal for space-constrained designs, and is available in Tape & Reel (TR) packaging for automated assembly.
