REF02BU datasheet by Texas Instruments

REF02BU Frequently Asked Questions (FAQs)

• What is the typical output impedance of the REF02BU?
  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.
• How does the REF02BU behave when the input voltage is below the minimum recommended value?
  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.
• Can I use the REF02BU in a high-temperature environment?
  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.
• How do I ensure the REF02BU is properly bypassed for noise reduction?
  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.
• What is the recommended layout and PCB design considerations for the REF02BU?
  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.
