Ultra LDO 1A Linear Regulator With
The maximum power dissipation is:
(T_J-max - T_A)
P_MAX =
R_ΘJA
Where T is the maximum allowable junction temperature (150°C), and T is the ambient temperature
J-max
A
suitable in application.
As a general rule, the lower temperature is, the better reliability of the device is. So the PCB mounting pad
should provide maximum thermal conductivity to maintain low device temperature.
