LDK320M-R ST LDO Regulator | SOT-23-5 | 200mA, 1% Accuracy

Product Overview

The LDK320M-R from STMicroelectronics is a high-performance low-dropout (LDO) voltage regulator designed for space-constrained applications. Housed in a compact SOT-23-5 package, it delivers up to 200 mA output current with excellent accuracy and low quiescent current. The device features a wide input voltage range from 2.5 V to 18 V and provides a fixed output voltage of 3.0 V with ±1% tolerance. Its low dropout voltage (typically 200 mV at 200 mA) ensures efficient operation even under low input-to-output voltage differentials. The LDK320M-R includes protection features such as thermal shutdown and current limiting, making it a reliable choice for various industrial, automotive, and consumer electronics.
