1 / 29 page 1/29 January 2004 s VERY LOW DROPOUT VOLTAGE (0.4V) s VERY LOW QUIESCENT CURRENT (TYP. 50 µA IN OFF MODE, 600µA IN ON MODE) s OUTPUT CURRENT UP TO 250 mA s LOGIC-CONTROLLED ELECTRONIC SHUTDOWN s 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; 12V s INTERNAL CURRENT AND THERMAL LIMIT s ONLY 2.2µF FOR STABILITY s AVAILABLE IN ± 1% (AB) OR 2% (C) SELECTION AT 25°C s SUPPLY VOLTAGE REJECTION: 70db TYP. FOR 5V VERSION s TEMPERATURE RANGE: -40 TO 125°C DESCRIPTION The L4931 series are very Low Drop regulators available in TO-220, SO-8, DPAK, PPAK and TO-92 packages 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. In PPAK and SO-8 packages a Shutdown Logic Control function is available 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. L4931 SERIES VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT SCHEMATIC DIAGRAM TO-220 SO-8 TO-92 DPAK PPAK |
