Product Summary

The LP2951CMMX is a micropower voltage regulator with very low quiescent current (75μA typ.) and very low dropout voltage (typ. 40mV at light loads and 380mV at 100mA). The LP2951CMMX is ideally suited for use in battery-powered system. Furthermore, the quiescent current of the LP2951CMMX increases only slightly in dropout, prolonging battery life.
