LMS1585ACSX-3.3/NOPB TI LDO Regulator | TO-263 (DDPAK-3) | 3.3V Output, 5A

Product Overview

The LMS1585ACSX-3.3/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments (TI), offering a fixed output voltage of 3.3V with a maximum output current of 5A. Housed in the TO-263 (DDPAK-3) package, this device is designed for applications requiring high efficiency, low noise, and excellent transient response. The LMS1585 series features a dropout voltage of typically 1.2V at full load, making it suitable for converting 5V rails to 3.3V with minimal power dissipation. With an operating junction temperature range of -40°C to +125°C, it ensures reliable performance in harsh environments.
