These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to network terminal ground. 2. Refer to Figures 1 and 2 to avoid exceeding the design maximum virtual junction temperature; these ratings should not be exceeded. Due to variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.

To determine the virtual junction temperature (TJ) relative to the device pin temperature, the following calculations should be used: TJ = PD x RθJP + TP, where PD is the internal power dissipation of the device and TP is the device pin temperature at the point of contact to the printed wiring board. The RθJP for the TL75LPxx series is 50.5°C/W. 600 400 200 0 25 50 75 100 800 1000 1200 125 150 1800 1600 1400 2000 2200 2400 MAXIMUM CONTINUOUS DISSIPATION vs FREE-AIR TEMPERATURE TA − Free-Air Temperature − °C 1200 800 400 0 25 50 75 100 1600 2000 2400 125 150 3600 3200 2800 4000 4400 4800 TC − Case Temperature − °C RθJA = 151°C/W RθJC = 31°C/W MAXIMUM CONTINUOUS DISSIPATION vs CASE TEMPERATURE Figure 1 Figure 2 |
