L5980  
0.7A step-down switching regulator  
Features  
„ 0.7A DC output current  
„ 2.9V to 18V input voltage  
„ Output voltage adjustable from 0.6V  
„ 250kHz switching frequency, programmable  
up to 1MHz  
VFQFPN8 3x3  
„ Internal soft-start and inhibit  
„ Low dropout operation: 100% duty cycle  
„ Voltage feed-forward  
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.  
„ Zero load current operation  
„ Over current and thermal protection  
„ VQFN3x3-8L package  
The input voltage can range from 2.9V to 18V,  
while the output voltage can be set starting from  
Applications  
0.6V to V . Having a minimum input voltage of  
2.9V, the device is suitable also for 3.3V bus.  
IN  
„ Consumer:  
STB, DVD, DVD recorder, car audio, LCD TV  
and monitors  
Requiring a minimum set of external components,  
the device includes an internal 250kHz switching  
frequency oscillator that can be externally  
adjusted up to 1MHz.  
„ Industrial:  
Chargers, car battery, PLD, PLA, FPGA  
„ Networking: XDSL, modems, DC-DC modules  
The QFN package with exposed pad allows  
„ Computer:  
reducing the R  
60°C/W.
