Description  
The L7980 is a step down switching regulator with  
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.  
Zero load current operation  
Overcurrent and thermal protection  
VFQFPN3x3-8L and HSOP8 package  
The input voltage can range from 4.5 V to 28 V,  
while the output voltage can be set starting from  
Applications  
0.6 V to V .  
IN  
Consumer:  
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.  
STB, DVD, DVD recorder, car audio, LCD TV  
and monitors  
Industrial:  
PLD, PLA, FPGA, chargers  
The QFN and the HSOP packages with exposed  
Networking: XDSL, modems, DC-DC modules  
pad allow reducing the R  
down to 60 °C/W  
thJA  
Computer:  
and 40 °C/W respectively.  
Optical storage, Hard disk drive, Printers,  
Audio/graphic cards
