Notes
1) Applies over full temperature range :–
T
J
=
–55 to +150°C for IP1R07A / IP1R07
T
J
=
0 to +125°C for IP3R07A / IP3R07
All other specifications apply at T
J
= 25°C unless otherwise stated.
2) Test conditions unless otherwise stated :–

O
= 5V , V
P

O
= 3V , I
OUT
= 3A.
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.
