DESCRIPTION
The KF00 series are very Low Drop regulators
availablein SO-8 package andina wide rangeof
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 battery powered systems. Shutdown Logic Control functionis available
(pin5, TTL compatible). This means that when
the deviceis used asa local regulator,itis
possibleto puta partof the boardin standby,
decreasing the total power consumption.It
requires onlya 2.2 μF capacitor for stability
allowing space and cost saving.
