Application circuit
Description
The L5980 is step down switching regulator with
1A current limited embedded power MOSFET, so
it is able to deliver in excess of 0.7A 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 V
IN
. Having a minimum input voltage of
2.9V, the device is suitable also for 3.3V bus.
Requiring a minimum set of external components,
the device includes an internal 250kHz switching
frequency oscillator that can be externally
adjusted up to 1MHz.
The QFN package with exposed pad allows
reducing the R
thJA
down to approximately
60°C/W.
