Current Limiting
The EL5106 and EL5306 have no internal current-limiting
circuitry. If the output is shorted, it is possible to exceed the
Absolute Maximum Rating for output current or power
dissipation, potentially resulting in the destruction of the
device.
Power Dissipation
With the high output drive capability of the EL5106 and
EL5306, it is possible to exceed the 125°C Absolute
Maximum junction temperature under certain very high load
current conditions. Generally speaking when R
about 25 , it is important to calculate the maximum junction
temperature (T
power supply voltages, load conditions, or package type
need to be modified for the EL5106 and EL5306 to remain in
the safe operating area. These parameters are calculated as
