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

VERY LOW DROPOUT VOLTAGE
(0.2 V TYP.)
VERY LOW QUIESCENT CURRENT
(TYP. 0.01µA IN OFF MODE, 280µA IN ON
MODE)
OUTPUT CURRENT UP TO 100mA
TWO LOGIC-CONTROLLED ELECTRONIC
SHUTDOWNS
OUTPUT VOLTAGES OF 2; 2.5; 3.0; 3.3; 4;
4.75; 4.85; 5; 5.5 V
INTERNAL CURRENT AND THERMAL LIMIT
ONLY 2.2µF FOR STABILITY
V
SUPPLY VOLTAGE REJECTION: 80dB (TYP)
TEMPERATURE RANGE: -40°C TO 125°C
OUT
TOLLERANCE ± 3% AT 25°C
VERY LOW DROP WITH INHIBIT
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.
