LF55AB regulators equivalent, very low drop voltage regulators.
and specially in battery powered systems. In the 5 pins configuration (PENTAWATT and PPAK) a Shutdown Logic Control func.
The LF00 series are very Low Drop regulators available in PENTAWATT, 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 .
