® KF00 SERIES VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT s s s s s s s s s s VERY LOW DROPOUT VOLTAGE (0.4V) VERY LOW QUIESCENT CURRENT (TYP. 50 µA IN OFF MODE, 500µA IN ON MODE) OUTPUT CURRENT UP TO 500 mA LOGIC-CONTROLLED ELECTRONIC SHUTDOWN OUTPUT VOLTAGES OF 1.25; 1.5; 2.5; 2.7; 3; 3.3; 3.5; 4; 4.5; 4.7; 5; 5.2; 5.5; 6; 8; 8.5; 12V INTERNAL CURRENT AND THERMAL LIMIT ONLY 2.2µF FOR STABILITY AVAILABLE IN ± 2% ACCURACY AT 25 oC SUPPLY VOLTAGE REJECTION: 70 db (TYP.) TEMPERATURE RANGE: -40 TO 125 oC 3 1 SO-8 DPAK DESCRIPTION The KF00 series are very Low Drop regulators available in SO-8 package and in a wide range of output voltages. The very Low Drop voltage (0.4V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems. SCHEMATIC DIAGRAM A Shutdown Logic Control function is available (pin 5, TTL compatible). 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.
