    ... SolarMagic Micropower Voltage Regulator General Description The SM72238 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 ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the SM72238 increases only slightly in dropout, prolonging battery life ...

    ... This is especially important in CMOS RAM keep-alive applications. A 1μF tantalum, ceramic or aluminum electrolytic capacitor should be placed from the SM72238 input to ground if there is more than 10 inches of wire between the input and the AC filter capacitor battery is used as the input. REDUCING OUTPUT NOISE In reference applications it may be advantageous to reduce the AC noise present at the output ...
