LM1085ISX-3.3 TI LDO Regulator | TO-263 | 3A, 3.3V Fixed Output

Product Overview

The LM1085ISX-3.3 from Texas Instruments is a high-performance low-dropout (LDO) voltage regulator capable of delivering up to 3A of output current with a fixed output voltage of 3.3V. Housed in the TO-263 (DDPAK-3) package, it offers excellent thermal performance and is designed for applications requiring low dropout voltage and fast transient response. The device features a dropout voltage of typically 1.5V at full load, making it suitable for converting 5V rails to 3.3V with minimal power loss. It includes built-in protection features such as current limiting and thermal shutdown, ensuring reliable operation under fault conditions.
