REF5020AIDG4 datasheet by Texas Instruments

REF5020AIDG4 Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF5020?
  The recommended output capacitor value is 10uF to 22uF, depending on the application and noise requirements. A larger capacitor can help reduce noise and improve stability, but may also increase the startup time.
• How do I ensure the REF5020 is properly powered up and stable?
  To ensure proper power-up and stability, the REF5020 requires a minimum of 1ms of power-up time, and the input voltage (VCC) should be stable and within the recommended operating range (2.7V to 5.5V) before the output voltage is valid.
• What is the thermal shutdown temperature of the REF5020?
  The thermal shutdown temperature of the REF5020 is typically around 150°C to 160°C, which is not explicitly stated in the datasheet. This is an important consideration for high-temperature applications.
• Can I use the REF5020 as a voltage regulator?
  No, the REF5020 is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage or provide a high current output.
• How does the REF5020 behave during power-down or brownout conditions?
  During power-down or brownout conditions, the REF5020 output voltage will decay to zero, and the device will enter a low-power state to conserve energy. When power is restored, the REF5020 will restart and output a stable voltage reference.
