SAFE AREA OF OPERATION
Due consideration should be given to operating conditions to avoid excessive thermal dissipation of the LP5996
or triggering its thermal shutdown circuit. When both outputs are enabled, the total power dissipation will be
P
D(LDO1)
+ P
D(LDO2)
where PD = (V
IN
- V
OUT
) x I
OUT
for each LDO
In general, device options which have a large difference in output voltage will dissipate more power with both
outputs enabled, due to the input voltage required for the higher output voltage LDO. In such cases, especially at
elevated ambient temperature, it may not be possible to operate both outputs at maximum current at the same
time.
