L4973 3.5A step down switching regulator

The L4973 is a step down monolithic power switching regulator delivering 3.5 A at fixed voltages of 3.3 V or 5.1 V and using a simple external divider output adjustable voltage up to 50 V. Realized in BCD mixed technology, the device uses an internal power D-MOS transistor (with a typical RDS(on) of.
