DESCRIPTION  
The LF00 series are very Low Drop regulators  
available in PENTAWATT, TO-220, TO-220FP,  
DPAK and PPAK package and in a wide range of  
output voltages.  
DPAK  
when the device is used as a local regulator, it is  
possible to put a part of the board in standby,  
decreasing the total power consumption. In the  
three terminal configuration the device has the  
same electrical performance, but is fixed in the ON  
state. It requires only a 2.2 µF capacitor for  
stability allowing space and cost saving.  
The very Low Drop voltage (0.45V) and the very  
low quiescent current make them particularly  
suitable for Low Noise, Low Power applications  
and specially in battery powered systems.  
In the 5 pins configuration (PENTAWATT and  
PPAK) a Shutdown Logic Control function is  
available (pin 2, TTL compatible). This means that
