SLR-342VR3F - ROHM Semiconductor

SLR-342VR3F Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a 2-layer PCB with a thermal via array under the IC to improve heat dissipation. A minimum of 5 thermal vias with a diameter of 0.3mm, spaced 1.2mm apart, is recommended.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it's essential to follow the recommended thermal design guidelines, use a heat sink if necessary, and consider derating the output current according to the ambient temperature.
• What is the maximum allowed voltage on the VIN pin?
  Although the datasheet specifies a maximum input voltage of 36V, it's recommended to limit the voltage on the VIN pin to 32V to ensure reliable operation and prevent damage to the internal components.
• Can I use the SLR-342VR3F in a battery-powered device?
  Yes, the SLR-342VR3F is suitable for battery-powered devices. However, it's essential to consider the quiescent current (IQ) and the shutdown current (ISHDN) to minimize power consumption and extend battery life.
• How do I optimize the output capacitor selection for stability and performance?
  For optimal performance and stability, ROHM recommends using a low-ESR ceramic capacitor (X5R or X7R) with a capacitance value between 10uF and 22uF, and a voltage rating of 50V or higher.
