L7980 Datasheet 2A step-down switching regulator

Manufacturer: STMicroelectronics

General Description

The L7980 device is a step-down switching regulator with a 2.5 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.

The input voltage can range from 4.5 V to 28 V, while the output voltage can be set starting from 0.6 V to VIN.

Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
