DESCRIPTION
The KF00 series are very Low Drop regulators
availablein SO-8 package and in a widerange 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 speciallyin batterypowered 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
allowingspace and cost saving.
