LM4040A20IDBZT datasheet by Texas Instruments

LM4040A20IDBZT Frequently Asked Questions (FAQs)

• What is the recommended capacitor value for the output capacitor?
  The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
• How do I ensure the LM4040A20IDBZT is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and avoid long traces and loops in the circuit.
• What is the maximum current I can draw from the LM4040A20IDBZT?
  The maximum output current of the LM4040A20IDBZT is 10mA, but it's recommended to limit the current to 5mA or less to maintain accuracy and stability.
• How does temperature affect the accuracy of the LM4040A20IDBZT?
  The LM4040A20IDBZT has a temperature coefficient of ±0.05%/°C, which means its output voltage will change by ±0.05% for every 1°C change in temperature.
• Can I use the LM4040A20IDBZT as a voltage regulator?
  No, the LM4040A20IDBZT is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
