LM385BDG4-1-2 Frequently Asked Questions (FAQs)

  • The typical output impedance of the LM385BDG4-1-2 is around 0.2 ohms, which is relatively low and makes it suitable for applications where a stable voltage reference is required.
  • The LM385BDG4-1-2 has a built-in power-on reset circuit that ensures a stable output voltage during power-up and power-down sequences. This helps to prevent unwanted voltage transients and ensures a reliable startup.
  • Yes, the LM385BDG4-1-2 is rated for operation up to 125°C, making it suitable for high-temperature applications. However, the output voltage may drift slightly with temperature, so it's essential to consider this in the design.
  • The LM385BDG4-1-2 can drive capacitive loads up to 10uF without oscillation or instability. However, it's recommended to add a series resistor to the output to prevent oscillation and ensure stable operation.
  • The LM385BDG4-1-2 has a bandwidth of around 100 kHz, making it suitable for low-to-medium frequency applications. For high-frequency applications, a different voltage reference may be more suitable.
