REF5020IDGKT datasheet by Texas Instruments

REF5020IDGKT Frequently Asked Questions (FAQs)

• What is the typical output impedance of the REF5020?
  The typical output impedance of the REF5020 is around 0.5 ohms.
• How do I ensure stability when using the REF5020?
  To ensure stability, use a 10uF capacitor between the output pin and ground, and a 1uF capacitor between the input pin and ground.
• What is the recommended input voltage range for the REF5020?
  The recommended input voltage range for the REF5020 is 4.5V to 18V.
• Can I use the REF5020 in a high-temperature environment?
  Yes, the REF5020 is rated for operation up to 125°C, but the accuracy and stability may degrade at high temperatures.
• How do I layout the PCB to minimize noise and ensure accurate voltage reference?
  Use a star-ground configuration, keep the REF5020 away from high-current paths, and use a ground plane to minimize noise and ensure accurate voltage reference.
