LP5990TMX-1.2/NOPB TI Linear Voltage Regulator | 4-DSBGA | 1.2V Fixed Output, 200mA

Product Overview

The LP5990TMX-1.2/NOPB is a low-dropout linear voltage regulator from Texas Instruments, designed to deliver a fixed 1.2V output with a maximum current of 200mA. Housed in a compact 4-DSBGA package, this device offers excellent line and load regulation, making it ideal for space-constrained applications requiring a stable and low-noise power supply. The LP5990 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.
