NOTE:
*1: Unless otherwise stated, V_IN=V_{OUT (T)} +1.0V, V_EN2=0V.
*2: V_{OUT (E)} = Actual output voltage (refer to the voltage table)
(ie. The output voltage when “V_{OUT (T)} +1.0V” is provided at the V_IN pin while maintaining a certain I_OUT value.
*3: Characteristics of the actual V_{OUT (E)} by nominal output voltage is shown in the voltage table.
*4: V_{OUT (T)} is nominal output voltage
*5: Vdif = V_IN1(*7)－V_OUT3(*6)
*6: V_{OUT 3} is a voltage equal to 98% of the V_{OUT (T)} when an amply stabilized input voltage is applied in V_{OUT (T)} +1.0V.
*7: V_IN1 is the input voltage when V_OUT3 appears while input voltage is gradually decreased.
*8: For XC6419Bx/Dx series only.
XC6419Ax/Cx series discharge with only Rx1 and Rx2 resistors as shown in the BLOCK DIAGRAMS.
