(TYP.)

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.

■

TEMPERATURE RANGE: -40 TO 125 °C

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
