DESCRIPTION
The LF00 series are very Low Drop regulators available in PENTAWA TT, TO-220, TO-220FP , 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, Lo w Power applications and specially in battery powered systems. In the 5 pins configuration (PENTAW AT T 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 tot al power consumption. In t he three terminal configuration the device has the same electricalperformance, but is fixed in the ON state. It requires only a 2.2 µF capacitor for stability allowing space and cost saving.
