ST763ACN

Voltage Regulators - DC DC Switching Regulators Overview

The ST763ACN is a step-down switching regulator from STMicroelectronics, operating within a supply voltage range of 3.3V to 11V to deliver a fixed 3.3V output. It provides up to 500mA of output current with typical efficiency of 90% and a quiescent current of 0.6mA in active mode. The device utilizes PWM current mode control for precise regulation and features cycle-by-cycle current limiting, under-voltage lockout, and programmable soft-start. It operates at a frequency of 200kHz and is housed in an SO-8 package.
