LT1004CDR-2-5 datasheet by Texas Instruments

LT1004CDR-2-5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LT1004CDR-2-5 to minimize noise and ensure accurate voltage reference?
  A good PCB layout practice is to keep the LT1004CDR-2-5 away from high-current carrying traces and noisy components. Use a solid ground plane and keep the input and output traces short and direct. Avoid routing digital signals near the voltage reference.
• How do I ensure the LT1004CDR-2-5 is properly decoupled to prevent oscillations?
  Use a 10nF to 100nF ceramic capacitor between the input pin and ground, and a 10uF to 22uF electrolytic capacitor between the output pin and ground. Place the capacitors as close to the device as possible.
• What is the maximum allowed temperature range for the LT1004CDR-2-5?
  The LT1004CDR-2-5 is rated for operation from -40°C to 125°C. However, the accuracy and stability of the voltage reference may degrade at extreme temperatures.
• Can I use the LT1004CDR-2-5 as a voltage regulator?
  No, the LT1004CDR-2-5 is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the current drive capability to regulate voltage.
• How do I calculate the output impedance of the LT1004CDR-2-5?
  The output impedance of the LT1004CDR-2-5 is typically around 10 ohms. You can calculate it using the formula: Zout = (ΔVout / ΔIout) where ΔVout is the change in output voltage and ΔIout is the change in output current.
