RQ6A045APTCR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad size of 2.5mm x 2.5mm with a minimum of 10 thermal vias (0.3mm diameter) to ensure efficient heat dissipation. Additionally, a solid copper plane on the bottom layer can help to further reduce thermal resistance.
  • To ensure stable operation with a high-impedance input source, ROHM recommends adding a 1kΩ to 10kΩ resistor in series with the input pin to reduce oscillation and noise. Additionally, a 10nF to 100nF capacitor can be added in parallel with the input pin to filter out high-frequency noise.
  • The maximum allowed voltage on the enable pin is 6V, which is the same as the maximum supply voltage (VCC). Applying a voltage higher than 6V may damage the device.
  • The power dissipation of the RQ6A045APTCR can be calculated using the formula: Pd = (Vin - Vout) x Iout + Vin x Iq, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. ROHM provides a power dissipation calculator on their website to simplify this calculation.
  • ROHM recommends using a 10uF to 22uF ceramic capacitor (X5R or X7R type) with a voltage rating of 10V or higher as the input capacitor. This helps to filter out input noise and ensure stable operation.
