LM317M 2 Absolute Maximum Ratings Electrical Characteristics (VI-VO = 5V, IO = 0.1A, 0 °C ≤ TJ ≤ +125°C, PDMAX = 7.5W, unless otherwise specified) Note: 1. Thermal resistance test board Size: 76.2mm * 114.3mm * 1.6mm(1S0P) JEDEC standard: JESD51-3, JESD51-7 2. Assume no ambient airflow. 3. Load and Line regulation are specified at constant junction temperature. Change in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. 4. CADJ, when used, is connected between the adjustment pin and ground.
