1 _{Vi min will not be as stated, if Vo is increased above Vo nom by use of the R or Trim input. If the output voltage is set to a higher value, Vi min}
will be proportionally increased.
2 _{Measured with a resistive and the max. admissible capacitive load.}
3 _{Measured with a lead length of 0.1 m, leads twisted. Double-output models with both outputs in parallel. 70 /110 IMX7 models need an}
external capacitor at the input, e.g. 1 µF film or ceramic.
