Measured with a resistive and the max. admissible capacitive load.
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 F film or ceramic.
Source impedance according to ETS 300132-2, version 4.3, at V
The DC-DC converter shuts down automatically at approx. 38 V.
