LM385DRG4-2-5 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-ground configuration, with the voltage reference pin connected to a quiet analog ground, and the output capacitor placed close to the output pin to minimize noise and oscillations.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the output capacitor close to the output pin. Also, avoid using long traces or wires between the output pin and the capacitor, and keep the voltage reference pin connected to a quiet analog ground.
  • The LM385DRG4-2-5 is rated for operation from -40°C to 125°C, but the accuracy and stability of the voltage reference may degrade at extreme temperatures. Consult the datasheet for detailed temperature-related specifications.
  • No, the LM385DRG4-2-5 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 in a power supply circuit.
  • The output impedance of the LM385DRG4-2-5 is typically around 10 ohms, but it can vary depending on the output capacitance and the frequency of operation. Consult the datasheet for detailed impedance specifications and calculation methods.
