* ) VOUT1=3.0V, VOUT2=-0.3V, IOUT2=1mA, unless otherwise specified. (See Typical Application)

*1 ) Adjustable by external resistors to -30V.

*2 ) “Minimum Operating Voltage”means a voltage for the “VOUT1” pin.

*3 ) This value shows only the supply current of DC/DC2, not include the supply current of external resistors.
