MCR03EZPJ2R2 - ROHM Semiconductor

MCR03EZPJ2R2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM 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.
• How do I ensure stable operation over the entire operating temperature range?
  To ensure stable operation, ROHM recommends using a bypass capacitor (e.g., 10uF) between the VIN and GND pins, and a decoupling capacitor (e.g., 100nF) between the VOUT and GND pins.
• What is the maximum allowed voltage on the VIN pin?
  Although the datasheet specifies a maximum input voltage of 5.5V, ROHM recommends limiting the VIN voltage to 5V or less to ensure reliable operation and prevent damage to the device.
• Can I use the MCR03EZPJ2R2 in a high-temperature environment?
  While the MCR03EZPJ2R2 is rated for operation up to 125°C, ROHM recommends derating the output current and power dissipation to ensure reliable operation in high-temperature environments.
• How do I calculate the power dissipation of the MCR03EZPJ2R2?
  Power dissipation can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + VIN x IQ, where IQ is the quiescent current. ROHM provides a power dissipation calculator on their website to simplify this calculation.
