Typical Applications (continued)
8.2.7 High Current Lamp Driver Protection
A simple constant current source with protection can be designed by controlling the impedance between the
lamp and ground. The LM1084-ADJ shown in Figure 22 makes use of an external TTL or CMOS input to drive
the NPN transistor. This pulls the output of the regulator to a few tenths of a volt and puts the part into current
limit. Releasing the logic will reduce the current flow across the lamp into the normal operating current thereby
protecting the lamp during startup.

8.2.8 Battery Backup Regulated Supply
A regulated battery backup supply can be generated by using two fixed output voltage versions of the part as
shown in Figure 23. The top regulator supplies the Line voltage during normal operation, however when the input
is not available, the second regulator derives power from the battery backup and regulates it to 5 V based on the
LM1084-5.0. The diodes prevent the rails from back feeding into the supply and batteries.
