REF02CESA+ Frequently Asked Questions (FAQs)

• What is the recommended input voltage range for the REF02CESA+?
  The recommended input voltage range for the REF02CESA+ is 4.5V to 36V. However, it can operate with input voltages as low as 3.5V, but with reduced accuracy and stability.
• How do I ensure the REF02CESA+ is stable and accurate?
  To ensure stability and accuracy, it's essential to decouple the input voltage with a 10uF capacitor, use a low-ESR output capacitor (e.g., 10uF), and keep the device away from high-frequency noise sources.
• What is the output impedance of the REF02CESA+?
  The output impedance of the REF02CESA+ is typically around 0.5 ohms, which is relatively low and suitable for most applications.
• Can I use the REF02CESA+ in a high-temperature environment?
  Yes, the REF02CESA+ is rated for operation from -40°C to 125°C, making it suitable for high-temperature applications. However, the accuracy and stability may degrade at extreme temperatures.
• How do I protect the REF02CESA+ from reverse voltage?
  To protect the REF02CESA+ from reverse voltage, use a diode (e.g., 1N4001-1N4007) in series with the input voltage to prevent reverse voltage from damaging the device.
