LP2951-N Datasheet

Series of Adjustable Micropower Voltage Regulators


The LP2950-N and LP2951-N are micropower voltage regulators with very low quiescent current (75μA typical) and very low dropout voltage (typical 40 mV at light loads and 380 mV at 100 mA). They are ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the LP2950-N/LP2951-N increases only slightly in dropout, prolonging battery life.
