Application Information (continued)

Thermal Consideration

The maximum junction temperature should be restricted to +150°C under normal operating conditions. The maximum allowable power dissipation

PD(MAX) can be calculated as:

PD(MAX) = (TJ(MAX) - TA) / θJA

where,

TJ(MAX) is the maximum operating junction temperature.

TA is the ambient temperature of the device.

θJA is the junction-to-air thermal impedance.

Board Layout

Good PCB layout is important for improving the thermal performance of the device. All trace lengths should be kept as short as possible. Place input

and output capacitors close to the device to minimize the effects of parasitic inductance. The input and output PCB traces should be as wide as

possible.
