DESCRIPTION
The KF00 series are very Low Drop regulators
availablein SO-8 package and in a wide range of
output voltages.
The very Low Drop voltage (0.4V) and the very
low quiescent current make them particularly
SO-8
DPAK
suitable for Low Noise, Low Power applications
and specially in battery powered systems.
A Shutdown Logic Control function is available
(pin 5, 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
total power consumption. It requires only a 2.2 µF
capacitor for stability allowing space and cost
saving.
