AME8818
Low Dropout
300mA CMOS Regulator
n Electrical Specifications
V_IN = V_OUT(NOM) + 1V or V_IN = 2.5V, if V_OUT(NOM) <= 2.0V, I_OUT = 1mA, V_EN = V_IN and C_OUT = C_IN = 1µF, Typical values at
T_A = 25^oC, unless otherwise noted.

Note 1: V_IN(MIN)=V_OUT+V_DROP or V_IN(min)=2.5V, whichever is greater.
Note 2: For V_OUT below 2.0V, Dropout Voltage is the input to output differential.
Note 3: For V_OUT below 1.5V, the minimun input. Voltage is 3.0V.
