NOTE:
* 1: Unless otherwise stated, VIN=VOUT(T)Ê´1.0V.
* 2: VOUT(T) = Specified output voltage
* 3: VOUT(E) = Effective output voltage
(I.e. the output voltage when an amply stabilized "VOUT(T)Ê´1.0V" is provided at the VIN pin while maintaining a certain IOUT value.)
High Speed (HS) mode: The voltage of VGOH or more is input to the GO pin, or the voltage of VGOL or less is input to the GO pin
when the output current is IGO or more.
Power Save (PS) mode: The voltage of VGOL or less is input to the GO pin when the output current is IGOR or less.
* 4: Vdif={VIN1^(*6)-VOUT1^(*5)}
* 5: 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.
* 6: VIN1=The input voltage when VOUT1 appears as Input Voltage is gradually decreased.
* 7: With the GO pin input voltage, the fixed HS mode or Green Operation (GO) is selectable.
* 8: For the XC6207B series only. The XC6207A series discharges by resistors R1 and R2 only as shown in the block diagrams.
* 9: The rated value of the output voltage when VOUT(T) ʽ1.5V is shown below.
HS mode : VOUT(T) -30mVʽVOUT(E)ʽVOUT(T) +30mV
PS mode : VOUT(T) -45mVʽVOUT(E)ʽVOUT(T)+30mV
*10: Recommended conditions for CIN and CL
1.2VʽVOUT(T)ʻ1.8V: CIN=1.0ЖF, CL=4.7ЖF (ceramic cap.)
1.8VʽVOUT(T)ʻ2.5V: CIN=1.0ЖF, CL=1.0ЖF (ceramic cap.)
2.5VʽVOUT(T)ʽ5.0V: CIN=2.2ЖF, CL=1.0ЖF (ceramic cap.)
