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

INTERNAL CURRENT AND THERMAL LIMIT

ONLY 2.2 µF FOR STABILITY

AVAILABLE IN ± 2% ACCURACY AT 25 °C

SUPPLY VOLTAGE REJECTION: 70 db

(TYP.)

TEMPERATURE RANGE: -40 TO 125 °C

VOLTAGE REGULATORS WITH INHIBIT

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.
