REF3020AIDBZRG4 datasheet by Texas Instruments

REF3020AIDBZRG4 Frequently Asked Questions (FAQs)

• What is the typical output voltage tolerance of the REF3020?
  The typical output voltage tolerance of the REF3020 is ±0.05% (±5 mV) at 25°C.
• How do I ensure the REF3020 is stable and accurate?
  To ensure stability and accuracy, decouple the input and output pins with 10 μF capacitors, and use a low-ESR capacitor (e.g., X5R or X7R) for the output capacitor.
• What is the recommended input voltage range for the REF3020?
  The recommended input voltage range for the REF3020 is 4.5 V to 18 V, but it can operate up to 20 V with reduced accuracy.
• How does temperature affect the REF3020's accuracy?
  The REF3020 has a temperature coefficient of ±10 ppm/°C, which means its output voltage can vary by up to ±10 ppm (0.001%) for every 1°C change in temperature.
• Can I use the REF3020 in a high-reliability application?
  Yes, the REF3020 is suitable for high-reliability applications, as it is built with a proprietary BiCMOS process and has a proven track record in aerospace, automotive, and industrial applications.
