L5981 Datasheet (STMicroelectronics) - 1A step-down switching regulator

L5981, 1A step-down switching regulator

The L5981 is step down switching regulator with 1.5A current limited embedded power MOSFET, so it is able to deliver in excess of 1A DC current to the load depending on the application condition.

The input voltage can range from 2.9V to 18V, while the output voltage can be set starting from 0.6V to
