LD2985BM18R ST LDO Regulator | SOT-23-5 | 1.8V Output, 150mA

Product Overview

The LD2985BM18R from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 1.8V output voltage. Housed in a compact SOT-23-5 package, it delivers up to 150mA of output current with excellent line and load regulation. The device features a low dropout voltage of typically 0.2V at full load, making it ideal for battery-powered and portable electronics. Its ultra-low quiescent current (typically 30µA) and shutdown mode (less than 1µA) contribute to extended battery life. The LD2985BM18R also includes internal current limiting and thermal shutdown protection for robust operation.
