ST715MR ST Linear Voltage Regulator | SOT-23-5 | 85mA, 1.2V to 5.5V

Product Overview

The ST715MR is a high-performance, low-dropout linear voltage regulator from STMicroelectronics, designed for space-constrained and power-sensitive applications. Housed in a compact SOT-23-5 package, it delivers up to 85mA output current with a dropout voltage as low as 200mV at full load. The device operates over a wide input voltage range from 2.5V to 5.5V and provides a fixed output voltage of 1.2V, 1.8V, 2.5V, 3.3V, or 5.0V (adjustable version available). With excellent line and load regulation, low quiescent current (typically 1.5µA in shutdown), and built-in protection features, the ST715MR is ideal for battery-powered equipment, portable devices, and industrial sensors.
