Thermal protection limits total power dissipation in the
device. When the junction temperature exceeds
T
J
=+150
°
C, the thermal sensor generates a logic sig-
nal to turn off the pass transistor and allows IC to
cool. When the IC
’
s junction temperature is down by
10
°
C, the thermal sensor will turn the pass transistor
on again, resulting in a pulsed output during continu-
ous thermal protection. Thermal protection is designed
to protect the APL5301/2 in the event of fault
conditions. For continuous operation, do not exceed
the absolute maximum junction temperature of
T
J
=+150
°
C.

The thermal resistance of the case to circuit board,
and the rate of air flow all control the APL5301/2

s
maximum power dissipation. The power dissipation
across the device is P
D
= I
OUT
(V
IN
-V
OUT
) and the maxi-
mum power dissipation is:
P
DMAX
= (T
J
-T
A
) / (
θ
JC
+
θ
CA
)
where T
J
-T
A
is the temperature difference between the
junction and ambient air,
θ
JC
is the thermal resistance
of the package, and
θ
CA
is the thermal resistance
through the printed circuit board, copper traces, and
other materials to the ambient air.
The GND pin of the APL5301 and APL5302 that the
packages ard SOT-23-5, SOT-89-5 AND SOP-8 pro-
vide an electrical connection to ground and channel-
ing heat away. If power dissipation is large, connect
the GND pin to ground using a large pad or ground
plane, can improve the problem of over heat of IC.
