2: VOUT (T) = Nominal output voltage. (Shown in the voltage chart E-0)
3: Vdif = {VIN1-VOUT1} VIN1 is the input voltage when VOUT1 appears at the VOUT pin while input voltage is gradually decreased. VOUT1 is the voltage equal to 98% of the HS mode output voltage when an amply stabilized VOUT (T) +1.0V are supplied to the VIN pin.
4: For the XC6220B/D series only. The XC6220A/C series (semi-custom) discharges by only R1 and R2 resistors as shown in the block diagrams.
