NCP130 Datasheet, PDF (5/9 Pages) ON Semiconductor – 300mA, Very Low Dropout Bias Rail CMOS Voltage Regulator

NCP130
TYPICAL CHARACTERISTICS
At T_J = +25°C, V_IN = V_OUT(TYP) + 0.3 V, V_BIAS = 2.7 V, V_EN = V_BIAS, V_OUT(NOM) = 1.05 V, I_OUT = 300 mA,
C_IN = 1 mF, C_BIAS = 0.1 mF, and C_OUT = 1 mF (effective capacitance), unless otherwise noted.
