Product Summary

The SC189ASKTR is a high efficiency, synchronous step-down regulator providing up to 1.5A output current in either an ultra-small 2mm x 2mm, low profile package or a low cost SOT23-5 package. The SC189ASKTR 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. The applications of the SC189ASKTR include Bluetooth Radios, DSC and PMPs, GPS Devices, xDSL Systems, POL Regulators, Portable HDD, Wireless LAN.
