LD39020ADM30R ST LDO Regulator | SOT-23-5 | 200mA, 1.2V to 5.5V

Product Overview

The LD39020ADM30R is a high-performance, low-dropout (LDO) voltage regulator from STMicroelectronics, designed to deliver up to 200 mA output current with excellent accuracy and low quiescent current. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring a stable and clean power supply. The LD39020ADM30R offers a fixed output voltage of 3.0V, with an input voltage range from 1.2V to 5.5V, making it suitable for battery-powered devices and portable electronics. Its low dropout voltage (typically 200 mV at full load) ensures efficient operation even when the input voltage is close to the output voltage. The device also features enable logic, short-circuit protection, and thermal shutdown, enhancing system reliability.
