Description

The SC4626 is a high efficiency, synchronous step-down regulator providing up to 1A output current in a SOT23-5 package. The device requires only three external filter components for a complete step-down regulator solution. The input voltage range is 2.9 to 5.5V with either factory programmed outputs from 1.0 to 3.3V or adjustable output via an external resistor divider.
