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
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.
