LP4950C-5V and LP4951C
Adjustable Micropower Voltage
Regulators
General Description
The LP4950C and LP4951C are micropower voltage
regulators with very low quiescent current (75µA typ.
) and very low dropout voltage (typ.
40mV at light loads and 380mV at 100mA).
They are ideally suited for use in battery-powered systems.
Furthermore, the quiescent current of the LP4950C/LP4951C increases only slightly in dropout, prolonging battery life.
The LP4950C in the popular 3-pin TO-92 package is pin compatible with older 5V
regulators.
The 8-lead LP4951C is available in a plastic surface mount package and offers additio...
