Power Dissipation
The power dissipation in the LT6654 is dependent on VIN,
load current and the package. The LT6654 package has
a thermal resistance, or θJA, of 192°C/W. A curve that
illustrates allowed power dissipation versus temperature
for the 6-lead SOT-23 package is shown in Figure 9. The
power dissipation of the LT6654-2.5 as a function of input
voltage is shown in Figure 10. The top curve shows power
dissipation with a 10mA load and the bottom curve shows
power dissipation with no load. When operated within
its specified limits of VIN = 36V and sourcing 10mA, the
LT6654-2.5consumesabout335mWatroomtemperature.
The power-derating curve in Figure 9 shows the LT6654-
2.5 can only safely dissipate 130mW at 125°C, which is
less than its maximum power output. Care must be taken
when designing the circuit so that the maximum junction
temperature is not exceeded. For best performance, junc-
tion temperature should be kept below 125°C.
The LT6654 includes output current limit circuitry, as well
as thermal limit circuitry, to protect the reference from
damage in the event of excessive power dissipation. The
LT6654 is protected from damage by a thermal shutdown
circuit. However, changes in performance may occur as
a result of operation at high temperature.
Hysteresis
The hysteresis data is shown in Figure 11. The LT6654 is
capable of dissipating relatively high power. For example,
with a 36V input voltage and 10mA load current applied
to the LT6654-2.5, the power dissipation is PD = 33.5V
10mA = 335mW, which causes an increase in the die
temperature of 64°C. This could increase the junction
temperature above 125°C (TJMAXis150°C)andmaycause
the output to shift due to thermal hysteresis.
