0°C ≤ TJ ≤ 100°C

VI = 11 V, See note

IO = 10 mA

VI = 10 V ~ 20 V, IO = 10 mA

VI = 11 V, IO = 0 A ~ 1.0 A

IO = 0.5 A

IO = 1.0 A

VI = 11 V, IO = 0 mA, VE = 2.0 V

VI = 11 V, VE = 0 V

VE = 2.0 V

VE = 0 V

VI = 11 V, 100 Hz ≤ f ≤ 120 Hz

IO = 10 mA

Typical values are given for circuit design information only.

Note: Output short-circuit current is at point where output voltage has decreased 5%.
