LM385Z-1.2 datasheet by Linear Technology

LM385Z-1.2 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM385Z-1.2?
  The maximum operating temperature range for the LM385Z-1.2 is -40°C to 125°C.
• Can I use the LM385Z-1.2 as a voltage reference for high-current applications?
  No, the LM385Z-1.2 is not designed for high-current applications. It's intended for low-power, low-voltage reference applications. For high-current applications, consider using a voltage regulator like the LM317 or a dedicated high-current voltage reference.
• How do I ensure the LM385Z-1.2 is stable and doesn't oscillate?
  To ensure stability, follow proper PCB layout practices, use a 10nF to 100nF bypass capacitor between the input pin and ground, and avoid using long traces or wires that can introduce inductance.
• Can I use the LM385Z-1.2 as a voltage regulator?
  No, the LM385Z-1.2 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it doesn't have the capability to regulate voltage like a voltage regulator IC.
• What is the typical output impedance of the LM385Z-1.2?
  The typical output impedance of the LM385Z-1.2 is around 10 ohms to 20 ohms, which is relatively low and suitable for most applications.
