Ta = 75°C

Calculation of RthJA,max:

PD =(VIN – VOUT) x IOUT + VIN x Iq

= (13.5V – 5V) x 100 mA + 13.5 V x 3.5 mA

= 0.897 W

RthJA,max =(Tj,max – Ta) / PD

= (150°C – 75°C) / 0.897 W

= 83.61 K/W

As a result, the PCB design must ensure a thermal resistance RthJA lower than 83.61 K/W. According to

“Thermal resistance” on Page 8, at least 300 mm² heatsink area is required on the FR4 1s0p PCB, or the FR4

2s2p board can be used.
