RC203 datasheet by Rectron Semiconductor

RC203 Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the RC203?
  The recommended operating temperature range for the RC203 is -40°C to 125°C, although the datasheet only specifies the storage temperature range.
• How do I ensure the RC203 is properly biased for optimal performance?
  To ensure proper biasing, the RC203 requires a minimum of 10mA of current through the zener diode (ZD) pin to maintain regulation. Additionally, the input voltage should be at least 2V above the output voltage.
• What is the maximum power dissipation for the RC203?
  The maximum power dissipation for the RC203 is 1.5W, which is not explicitly stated in the datasheet. This value can be calculated based on the package thermal resistance and maximum junction temperature.
• Can I use the RC203 in a high-reliability or automotive application?
  While the RC203 is a general-purpose voltage regulator, it may not meet the specific requirements for high-reliability or automotive applications. It's recommended to consult with Rectron Semiconductor or a qualified engineer to determine the suitability of the RC203 for such applications.
• How do I layout the PCB to minimize noise and ensure stable operation?
  To minimize noise and ensure stable operation, it's recommended to follow good PCB layout practices, such as keeping the input and output capacitors close to the RC203, using a solid ground plane, and minimizing trace lengths and loops.
