Using a LM1084IS-ADJ as a load regulator in a circuit. 14vdc in, 0.200 ohm resistor between output and load, load sense line back to the adj pin. Load is only applied for 100 msec. Everything works fine until load gets above 6.2 amps. At 6.2 amps output starts to oscillate, by 6.5 amps fully oscillating. Should device be doing this? is it going into a short circuit/overload mode?
