Notes

1) Applies over full temperature range:–

0 to +125°C for IP3R18A–05 / IP3R18–05

2) Test conditions unless otherwise stated:–

Although Power Dissipation is internally limited, these specifications apply for Power Dissipation up to 50W.

3) Load and Line regulation are electrically independent and are measured using pulse techniques at low duty cycle in order to

maintain constant junction temperature. To determine the effects on the output voltage due to device heating, refer to thermal

regulation specification.
