RB168LAM-30TR - ROHM Semiconductor

RB168LAM-30TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a thermal pad size of at least 2mm x 2mm, with multiple vias to the ground plane to ensure good heat dissipation. A thermal resistance of 10°C/W or less is recommended.
• How do I ensure reliable operation at high temperatures?
  ROHM recommends derating the output current by 1.5mA/°C above 50°C to ensure reliable operation. Additionally, ensure good thermal design and consider using a heat sink if necessary.
• What is the recommended input capacitor value and type?
  ROHM recommends a 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric, placed as close to the VIN pin as possible, to ensure stable operation.
• Can I use this regulator in a high-vibration environment?
  Yes, the RB168LAM-30TR is designed to withstand vibrations up to 10G, but ensure that the PCB is properly secured and the component is soldered correctly to prevent mechanical stress.
• How do I protect the regulator from overvoltage and undervoltage conditions?
  ROHM recommends using a TVS diode or a voltage clamp circuit to protect the regulator from overvoltage conditions. For undervoltage conditions, consider using a voltage supervisor or a reset IC to ensure proper system operation.
