L7985TR ST Power Management IC | - | 3.3V Output, 1.5A Current

Product Overview

The L7985TR from STMicroelectronics is a high-efficiency step-down switching regulator designed for applications requiring up to 1.5A output current. It operates from an input voltage range of 4.5V to 28V and provides a fixed 3.3V output voltage. The device integrates a power MOSFET and features current-mode control for fast transient response and stable operation. Its compact package and minimal external components make it ideal for space-constrained designs.
