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,

280µA in ON MODE) make them particularly

suitable for Low Noise, Low Power applications

and specially in battery powered systems.

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 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.
