XC6404 EV / EX Series

Ta=25

(NOTE 1) Unless otherwise stated, VIN=VOUT(T)+1.0V

(NOTE 2) VROUT(T)=Specified VR Output Voltage

(NOTE 4) Vdif={VIN1

(NOTE6)-VROUT1(NOTE5)}

(NOTE 5) A voltage equal to 98% of the VR Output Voltage whenever a stabilized VROUT1=IROUT{VROUT(T)+1.0V} is input.

(NOTE 6) VIN1=The Input Voltage when VOUT1, which appears as Input Voltage is gradually decreased.

(NOTE 7) VDF (T) : Specified Detect Voltage value

(NOTE 8) VDF (E) : Actual Detect Voltage value. Refer to the E-0 chart on page 15 for VDF(T) less than 1.5V.

(NOTE 9) VD Output Current = Sink Current during detection.

When VROUT<1.75V, IROUT=10mA

(NOTE 3) VOUT(E)=Actual VR Output Voltage.

(i.e. the VR output voltage when "VROUT(T)+1.0V" is provided at the VIN pin while maintaining a certain IROUT value).
