DESCRIPTION

The LK115D00 series are very Low Drop regulators available in SO-8 package and in a wide range of output voltages. The very Low Drop voltage (0.2V) and the very low quiescent current (0.01µA in OFF MODE,

TOLLERANCE ±3% AT 25oC

VOLTAGE REGULATORS

SO-8

280µA in ON MODE) make them particularly suitable for Low Noise, Low Power applications and speciallyin battery poweredsystems. Both active HIGH and active LOW shutdown Logic Control are available (pin2 and 3). This means that when the device is used as a local regulator, it is possibleto 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.
