Description :

Description
The L5980 is a step-down switching regulator with a 1 A (min.) current limited embedded Power
MOSFET, so it is able to deliver in excess of 0.7 A DC current to the load depending on the
application condition. The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN. Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus. Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator thatcan be externally adjusted up to 1 MHz.
The VFQFPN8 package with an exposed pad allows reducing the RthJA down to approximately
60 °C/W.
