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.
