REF191GSZ Frequently Asked Questions (FAQs)

  • The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
  • To ensure stability and accuracy over temperature, it's essential to follow proper PCB layout and thermal management practices, and to consider the thermal coefficient of the reference voltage (TCV) when selecting components.
  • No, the REF191GSZ is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage. If you need a voltage regulator, consider using a separate device.
  • The minimum input voltage required for the REF191GSZ is 4.5V, but it's recommended to use a minimum of 5V to ensure proper operation.
  • To minimize noise and ripple on the input voltage, use a low-pass filter or a voltage regulator with a low noise output, and consider adding decoupling capacitors close to the REF191GSZ.
