LDK320ADU120R ST LDO Regulator | SOT-89 | 200mA, 12V Output

Product Overview

The LDK320ADU120R from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 12V output. Housed in a compact SOT-89 package, it delivers up to 200mA of output current with excellent line and load regulation. This device features a very low dropout voltage (typically 200mV at full load) and a wide input voltage range from 2.5V to 18V, making it suitable for battery-powered and industrial systems. The LDK320ADU120R integrates protection features such as thermal shutdown and current limiting, ensuring reliable operation under fault conditions.
