It is also useful to calculate the junction of temperature of the BL9198 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 BL9198 can be calculated as: , 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<TJ(MAX) =125°C For this operating condition, TJ is lower than the absolute maximum operating junction temperature,125°C, so it is safe to use the BL9198 in this configuration. Layout considerations To improve ac performance such as PSRR, output noise, and transient response, it is recommended that the PCB be designed with separate ground planes for VIN and VOUT, with each ground plane connected only at the GND pin of the device.
