Description

The LK115XX series are very low drop regulators

available in SO-8 package and in a wide range of

output voltages.

The very low drop voltage (0.2 V) and the very low

quiescent current (0.01 µA in OFF MODE, 280 µA

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 (pin 2 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.

SO-8

It requires only a 2.2 µF capacitor for stability

allowing space and cost saving.
