Description  
Low dropout operation: 100 % duty cycle  
Voltage feed-forward  
The L5987 is a step down switching regulator with  
3.5 A (minimum) current limited embedded power  
MOSFET, so it is able to deliver up to 3 A current  
to the load depending on the application  
Zero load current operation  
Over current and thermal protection  
VFQFPN3x3-8L and HSOP8 package  
conditionals Section 5.7 and Section 5.8).  
The input voltage can range from 2.9 V to 18 V,  
while the output voltage can be set starting from  
Applications  
0.6 V to V . Having a minimum input voltage of  
IN  
Consumer:  
2.9 V, the device is suitable also for 3.3 V bus.  
STB, DVD, DVD recorder, car audio, LCD TV  
and monitors  
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.  
Industrial:  
PLD, PLA, FPGA, chargers  
Networking: XDSL, modems, DC-DC modules  
The QFN and the HSOP package with exposed  
Computer:  
pad allow reducing the R  
down to 60 °C/W  
thJA
