TTL Logic signal goes high 50-150 msec after 5 V output. It goes low at least 4 ms before loss of regulation

需要一个外部的触点（常开或常闭） ，以抑制输出

TTL logic goes high 50-150 msec after the output. It goes low when there is loss of regulation.

Compensates for 0.5 V lead drop minimum, will operate without remote sense connected. Reverse
