DESCRIPTION

The KF00 series are very Low Drop regulators
availablein SO-8 p ac kag e and in a wide ra nge of
output voltages.
The very Low D rop v oltage (0.4V) and the very
low quiescent current make them particularly

suitable for Low Noise, Low Power applications
and specially in battery powered system s .
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, dec reas ing the
total power c ons umption. It requi res only a 2.2 µF
capacitor for stability allowing space and cost
saving.
