DC/DC Converter 2
*
) VOUT1=5.0V, VOUT2=–3.0V, 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.
