Set the "Maximum Ambient Temperature" until it reaches TJ ("Max Junction Temperature"), which is the absolute limit for safe use of the regulator: <a href="http://www.daycounter.com/Calculators/Heat-Sink-Temperature-Calculator.phtml">Heat Sink Temperature Calculator</a> For example, With 12V source into a 3.3V LP2985 and a 30mA load, we are dissipating (12V-3.3V) * 0.03A = 0.261W. With a θJA of 206 �°C/W, a TJ of 150�°C, and 261mW we can safely use the chip without a heat sink up to 75�°C (=147.1�°C Junction Temperature).
