Logic Control
Power failure TTL logic signal goes high 100-500
msec after 5 V output; it goes low at
least 4 msec before loss of regulation
Remote inhibit Requires an external TTL Signal to
inhibit outputs
Remote sense Compensates for 0.5 V lead drop
minimum, will operate without remote
sense connected. Reverse connection
protection.
