ST715M33R ST LDO Regulator | SOT-23-5 | 3.3V Output, 85mA

Product Overview

The ST715M33R is a low-dropout (LDO) linear voltage regulator from STMicroelectronics, offering a fixed output voltage of 3.3V with a maximum output current of 85mA. Housed in a compact SOT-23-5 package, it is designed for space-constrained applications requiring low quiescent current and high accuracy. The device features a typical dropout voltage of 200mV at full load, making it suitable for battery-powered systems. With an operating input voltage range from 2.5V to 5.5V, it provides a stable output with ±2% accuracy over line, load, and temperature variations. The ST715M33R includes internal protection circuits such as current limiting and thermal shutdown, ensuring reliable operation in harsh environments.
