3 Description
The LP2952 and LP2953 are micropower voltage regulators with very low quiescent current (130 μA typical at 1-m A load) and very low dropout voltage (typically 60 m V at light load and 470 m V at 250-m A load current). They are ideally suited for batterypowered systems. Furthermore, the quiescent current...
