R1155N050B-TR-FE Frequently Asked Questions (FAQs)

  • Ricoh recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • To ensure stability, follow the recommended output capacitor values and ESR ranges in the datasheet. Additionally, keep the input capacitor close to the regulator and use a low-ESR capacitor for the output.
  • The maximum allowed input voltage ripple is 1Vp-p, but it's recommended to keep it below 0.5Vp-p to ensure stable operation and minimize output voltage variation.
  • The R1155N050B-TR-FE is rated for operation up to 125°C, but derating is required above 85°C. Consult the datasheet for derating curves and ensure proper thermal design to prevent overheating.
  • Use the formula: Pd = (Vin - Vout) x Iout. Then, calculate the junction temperature using the thermal resistance (Rth) and power dissipation: Tj = Tc + (Rth x Pd), where Tc is the case temperature.
