ROHM recommends a thermal pad design with a minimum size of 2.5mm x 2.5mm, and a thermal via array with a minimum of 9 vias, 0.3mm in diameter, and 1.5mm deep to ensure optimal heat dissipation.
Choose an input capacitor with a capacitance value between 1uF to 10uF, and a voltage rating of at least 2x the input voltage. A low ESR (Equivalent Series Resistance) capacitor, such as an X5R or X7R ceramic capacitor, is recommended for stability and noise reduction.
According to ROHM's application note, the maximum output current should be derated by 1.5mA/°C above 50°C ambient temperature to ensure reliable operation and prevent overheating.
Yes, the BD87B29FVM-CTR is AEC-Q100 qualified and suitable for automotive and high-reliability applications. However, additional testing and validation may be required to meet specific industry standards and requirements.
To ensure EMC, use a shielded layout, keep the input and output capacitors close to the regulator, and use a common-mode choke or ferrite bead on the input line. Additionally, follow ROHM's recommended PCB layout and design guidelines for EMC compliance.
