REF02BU Frequently Asked Questions (FAQs)

  • The typical output impedance of the REF02BU is around 0.2 ohms, which is relatively low and helps to minimize output voltage changes due to load current variations.
  • If the input voltage falls below the minimum recommended value of 4.5V, the REF02BU may not function properly and the output voltage may not be regulated. It's essential to ensure the input voltage is within the recommended range for proper operation.
  • While the REF02BU is rated for operation up to 125°C, its accuracy and stability may degrade at higher temperatures. It's essential to consider the temperature coefficient and ensure the device is properly heat-sinked if operating in high-temperature environments.
  • To minimize noise and ensure proper operation, it's recommended to bypass the REF02BU with a 10uF ceramic capacitor between the VIN and GND pins, and a 100nF ceramic capacitor between the VOUT and GND pins.
  • To minimize noise and ensure proper operation, it's recommended to follow good PCB design practices, such as keeping the input and output traces separate, using a solid ground plane, and placing the bypass capacitors close to the device.
