The test board is inserted inside a 0.3 m x 0.3 m x 0.3 m. Weak buoyancy induced flow, caused by the heated test board and package, create a controlled natural convection boundary condition that is insensitive to external disturbance in the testing lab. Description This document specifies the definition and construction of a two-resistor compact thermal model (CTM) from the JEDEC junction-to-case and junction-to-board thermal metrics. The guidance provided in this document only applies to thermal metrics defined in JEDEC standards JESD51-8 and JESD51-12. OPTIREG™linear voltage regulator TLS125D0EJ High-precision voltage tracker Features • 250 mA current capability • Very high tracking accuracy • Output voltage adjustable down to 2.0 V • Stable with ceramic output capacitors • Very low dropout voltage of typically 250 mV at 250 mA • Very low current consumption of 0.1 µA in standby mode temperature, as described in JESD51-8. (5) The junction-to-topcharacterization parameter, yJT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining qJA, using a procedure described in JESD51-2a(sections 6 and 7). (2) The junction-to-ambientthermal resistance under natural convection is obtained in a simulation on a JEDEC-standard,high-Kboard, as specified in JESD51-7,in an environment described in JESD51-2a. (3) The junction-to-case(top) thermal resistance is obtained by simulating a cold plate
