Parameter Rating
junction-to-ambient thermal resistance is highly dependent on the VIN to GND −0.3 V to +6.5 V application and board layout. In applications where high maximum VOUT to GND −0.3 V to VIN power dissipation exists, close attention to thermal board design EN to GND −0.3 V to VIN is required. The value of θJA may vary, depending on PCB material, ADJ to GND −0.3 V to VIN layout, and environmental conditions. The specified values of NC to GND −0.3 V to VIN θJA are based on a 4-layer, 4 inches × 3 inches, circuit board. Refer Storage Temperature Range −65°C to +150°C to JESD 51-7 and JESD 51-9 for detailed information on the Operating Junction Temperature Range −40°C to +125°C board construction.
