製品概要

概要

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 V_IN.

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.

The QFN and the HSOP packages with exposed pad allow reducing the R_thJAdown to 60 °C/W and 40 °C/W respectively.
