SO-8
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 碌A(chǔ) in OFF MODE, 280 碌A(chǔ)
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.
