REF200AU/2K5 datasheet by Texas Instruments

REF200AU/2K5 Frequently Asked Questions (FAQs)

• What is the typical output impedance of the REF200AU/2K5?
  The typical output impedance of the REF200AU/2K5 is around 0.2 ohms.
• How do I ensure the REF200AU/2K5 is stable and accurate?
  To ensure stability and accuracy, it's essential to decouple the input and output pins with capacitors, use a low-impedance power supply, and minimize noise and interference in the circuit.
• Can I use the REF200AU/2K5 in a high-temperature environment?
  The REF200AU/2K5 is rated for operation up to 125°C, but its accuracy and stability may degrade at high temperatures. It's recommended to derate the device's performance at temperatures above 85°C.
• How do I protect the REF200AU/2K5 from reverse voltage?
  To protect the REF200AU/2K5 from reverse voltage, use a diode (e.g., 1N4001-1N4007) in series with the input pin to prevent reverse voltage from damaging the device.
• Can I use the REF200AU/2K5 as a voltage regulator?
  No, the REF200AU/2K5 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
