DESCRIPTION The LF00 series 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. SCHEMATIC DIAGRAM

In the 5 pins 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
