STEVAL-ISA092V1: 3.3V @ 2A, 4.5 ~ 28V in

Summary

The L7980 is a step-down switching regulator with embedded Power MOSFET 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 minimal set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz
