LDK120C-R ST LDO Regulator | SOT-323-5 | 200mA, Low Dropout

Product Overview

The LDK120C-R from STMicroelectronics is a high-performance, low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact SOT-323-5 package, it delivers up to 200 mA output current with excellent line and load regulation. The device features a very low dropout voltage (typically 200 mV at 200 mA) and a wide input voltage range from 2.5 V to 6 V, making it ideal for battery-powered and portable electronics. The LDK120C-R offers high accuracy (±1% typical), low quiescent current (60 µA typical), and a shutdown mode for power saving. It includes internal current limit and thermal shutdown protection, ensuring reliable operation under fault conditions.
