LK115D00 SERIES VERY LOW DROP WITH INHIBIT VOLTAGE REGULATORS ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ 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 VOUT TOLLERANCE ± 3% AT 25°C SUPPLY VOLTAGE REJECTION: 80dB (TYP) TEMPERATURE RANGE: -40°C TO 125°C 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 SO-8 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.
