Figure 21. TPS76301 Adjustable LDO Regulator Programming
power dissipation and junction temperature
Specified regulator operation is assured to a junction temperature of 125
°
C; the maximum junction temperature allowable
to avoid damaging the device is 150
°
C. This restriction limits the power dissipation the regulator can handle in any given
application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation,
P
D(max)
, and the actual dissipation, P
D
, which must be less than or equal to P
D(max)
.
The maximum-power-dissipation limit is determined using the following equation:
PD(max)
TJmax
TA
RJA
Where:
T
J
max
is the maximum allowable junction temperature
R
θ
JA
is the thermal resistance junction-to-ambient for the package, see the dissipation rating table.
T
A
is the ambient temperature.
The regulator dissipation is calculated using:
PD
VI
VO
IO
Power dissipation resulting from quiescent current is negligible.
