LM2940SX-12 TI LDO Regulator | TO-263 | 1A, 12V Output

Product Overview

The LM2940SX-12 from Texas Instruments is a low-dropout (LDO) voltage regulator designed to deliver a fixed 12V output with a maximum output current of 1A. Housed in the TO-263 (DDPAK-3) package, this device offers excellent line and load regulation, making it suitable for a wide range of applications requiring a stable and efficient power supply. With a dropout voltage typically below 0.5V at full load, the LM2940SX-12 ensures reliable operation even when the input voltage is close to the output voltage.
