ROHM provides a recommended PCB layout in their application note (AN1911) for thermal optimization. It suggests using a thermal pad on the bottom of the package, connecting it to a large copper area on the PCB, and using thermal vias to dissipate heat efficiently.
To ensure reliability, follow the recommended operating conditions, derating, and thermal management guidelines provided in the datasheet. Additionally, consider using a thermistor or thermal sensor to monitor the device temperature and implement over-temperature protection if necessary.
ROHM recommends a soldering profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds. The device is compatible with lead-free soldering processes, and ROHM provides a detailed soldering profile in their application note (AN1911).
The RBQ20BM100ATL is not specifically designed for high-humidity environments. However, it is possible to use it in such conditions with proper precautions, such as conformal coating, hermetic sealing, or using a moisture-resistant package. Consult ROHM's application notes and environmental testing guidelines for more information.
The ESR of the internal capacitor is not explicitly stated in the datasheet. However, ROHM provides a Spice model for the device, which includes the internal capacitor's ESR. You can extract this value from the Spice model or contact ROHM's technical support for more information.
