NOTE:
* 1: Unless otherwise stated regarding input voltage conditions, VIN=VOUT(T)＋1.0V.
* 2: VOUT (E) = Effective output voltage (Refer to the voltage chart E-0 and E-1)
(I.e. the output voltage when HS mode and an amply stabilized "VOUT (T)＋1.0V" is provided at the VIN pin while maintaining a
certain IOUT value.)
* 3: The rated value of the setting output voltage VOUT(E) is shown in voltage chart E-0 and E-1)
* 4: VOUT (T) = Specified output voltage
* 5: Vdif={VIN1(*7)-VOUT1(*6)}
* 6: VOUT1=A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VOUT(T)+1.0V} is input in the HS mode.
* 7: VIN1=The input voltage when VOUT1 appears as input voltage is gradually decreased.
* 8: For the XC6221B series only. The XC6221A series discharges by resistors R1 and R2 only as shown in the block diagrams.
