DESCRIPTION
The KF00 series are very Low Drop regulators
available in 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.

DPAK
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.
