LM385Z-1.2/LFT4 Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and desired noise rejection. A larger capacitor value can provide better noise rejection, but may also increase the startup time.
  • Yes, the LM385Z-1.2/LFT4 can be used as a voltage reference for an ADC. However, it's essential to ensure that the reference voltage is stable and accurate, and that the ADC's input range is compatible with the LM385Z-1.2/LFT4's output voltage.
  • To ensure stability and prevent oscillation, it's crucial to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and avoid long traces or wires between the input and output pins. Additionally, adding a 10nF to 100nF capacitor between the output pin and ground can help to reduce noise and oscillation.
  • The maximum output current of the LM385Z-1.2/LFT4 is 10mA. Exceeding this current limit can cause the output voltage to drop or become unstable.
  • The LM385Z-1.2/LFT4 is rated for operation up to 125°C. However, the device's accuracy and stability may degrade at high temperatures. It's essential to consider the device's temperature coefficient and ensure that the operating temperature is within the specified range.
