1 If Vo is set above Vo nom by use of the R or Trim input, Vi min will be proportionately increased.
2 Measured with resistive and max. admissible capacitive load.
3 Source impedance according to ETS 300132-2, version 4.3.
4 Measured with a ceramic capacitor Ci directly across input; output lead length 0.1 m, leads twisted. Double-output models with both
outputs in parallel. Ci is specified in table 11.
5 Input undervoltage lockout at typ. 80% of Vi min.
