The BL9195 still works well with temperature. The junction to ambient theroutput capacitor of other types due to the mal resistance (θJA is layout dependent) for wide stable ESR range. Output capacitor of SOT-23-3 package is 250°C/W, SOT89-3 larger capacitance can reduce noise and package is 160°C/W, SOT-223-3 package improve load transient response, stability, is 60°C/W on standard JEDEC 51-3 and PSRR. The output capacitor should be thermal test board. The maximum power located not more than 0.5 inch from the dissipation at TA= 25°C can be calculated VOUT pin of the BL9195 and returned to a by following formula: clean analog ground. PD(MAX) = (125°C−25°C)/160 = 667mW Thermal Considerations (SOT89-3) Applications Information Thermal protection limits power dissipation in BL9195. When the operation junction temperature exceeds 165°C, the OTP circuit starts the thermal shutdown function turn the pass element off.

It is also useful to calculate the junction Step-Down of temperature of the BL9195 under a set of specific conditions. In this example let the Input voltage VIN=3.3V, the output current Io=300mA and the case temperature TA=40°C measured by a thermal couple during operation. The power dissipation for the VOUT=2.8V version of the BL9195 can be calculated as: Converter , PD = (3.3V−2.8V) ×300mA+3.6V×100uA =150mW And the junction temperature, TJ, can be calculated as follows: TJ=TA+PD×θJA=40°C+0.15W×250°C/W =40°C+37.5°C=77.5°C
