LMS1587IS-3.3/NOPB TI LDO Regulator | TO-263 (DDPAK-3) | 3A, 3.3V Fixed Output

Product Overview

The LMS1587IS-3.3/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 3.3V output with a maximum output current of 3A. Housed in a TO-263 (DDPAK-3) package, this device is designed for applications requiring low dropout voltage, fast transient response, and excellent line and load regulation. The NOPB designation indicates a lead-free (RoHS-compliant) package. With a dropout voltage of typically 1.1V at full load, it is ideal for converting from 5V or other higher voltage rails to a stable 3.3V supply.
