REF7012QFKHT Frequently Asked Questions (FAQs)

  • The recommended output capacitor value is 10uF to 22uF, with a minimum ESR of 5 ohms to ensure stability and noise reduction.
  • Decouple the REF7012QFKHT from the power supply using a 0.1uF to 1uF ceramic capacitor and a 10uF to 22uF electrolytic capacitor in parallel, placed as close as possible to the device.
  • The maximum allowed input voltage for the REF7012QFKHT is 18V, exceeding which may cause damage to the device.
  • The REF7012QFKHT has a soft-start feature that prevents output voltage overshoot during power-up, and it also has a built-in power-down feature that reduces current consumption to near zero when the input voltage falls below 2.5V.
  • Yes, the REF7012QFKHT is specified to operate from -40°C to 125°C, making it suitable for high-temperature applications, but it's essential to ensure proper thermal management and follow the recommended operating conditions.
