±1%(AB)OR ±2%(C)SELECTIONAT 25o Cs SUPPLY VOLTAGE REJECTION:80db (TYP.)sTEMPERATURE RANGE:-40TO 125o CDESCRIPTIONThe LF00series are very Low Drop regulators available in PENTAWATT,TO-220,ISOWATT220,DPAK and PPAK package and in a wide range of output voltages.The very Low Drop voltage (0.45V)and the very low quiescent current make them particularly suitable for Low Noise,Low Power applications and specially in battery powered systems.In the 5pins configuration (PENTAWATT and PPAK)a Shutdown Logic Control function is available (pin 2,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.In the three terminal configuration the device has the same electrical performance,but is fixed in the ON state.It requires only a 2.2µF capacitor for stability allowing space and cost saving.SCHEMATIC DIAGRAMPPAKDPAKPENTAWATTTO-220ISOWATT220®1/31ABSOLUTE
