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