The L6926 is a high efficiency monolithic synchronous step-down regulator from STMicroelectronics. It integrates a high voltage MOSFET and a synchronous rectifier and can operate at 100% duty cycle, delivering up to 800mA of continuous output current and regulating the output voltage from 0.6V to VIN. This device is designed using BCDV technology and has a low quiescent current (25μA) and shutdown current (0.2μA), making it very suitable for battery-powered equipment such as PDAs, handheld terminals, DSCs (digital still cameras) and cell phones.
