VERY LOW DROPOUT VOLTAGE (0.2V TYP.) VERY LOW QUIESCENT CURRENT (TYP. 0.01A IN OFF MODE, 280A IN ON MODE) OUTPUT CURRENT UP TO 100 mA TWO LOGIC-CONTROLLED ELECTRONIC SHUTDOWNS OUTPUT VOLTAGES OF 2; 2.5; 3; 3.3; 4; 4.75; 4.85; 5; 5.5V INTERNAL CURRENT AND THERMAL LIMIT ONLY 2.2F FOR STABILITY VOUT TOLLERANCE 3% AT 25 oC SUPPLY VOLTAGE REJECTION: 80 db (TYP.) TEMPERATURE RANGE: -40 TO 125 oC

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 (0.01A in OFF MODE,
280A 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 F capacitor for stability allowing space and cost saving.
