Vin On to Vout regulated (100% resistive load)
Remote ON to 10% Vout (50% resistive load)
1A/μS, 25% of full load change
1A/μS, 25% of full load change
Pin open = OFF

Vin = 12V; Iout = 2.22A
98% of Vnom., after warmup
Output shorted to ground, no damage
Current limiting
Vin = min. to max. Vout = nom.
Iout = min. to max. Vin = nom.
