LM385PWR-2-5 Frequently Asked Questions (FAQs)

  • The minimum input voltage required is 4.5V, but it's recommended to use a minimum of 5V to ensure proper operation and to account for any voltage drops in the circuit.
  • To ensure output voltage stability, it's essential to provide a stable input voltage, minimize thermal gradients, and use a low-ESR capacitor (e.g., 10uF) between the OUT and ADJ pins. Additionally, consider using a thermally conductive material to mount the device.
  • No, the LM385PWR-2.5 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it does not have the capability to regulate voltage like a linear voltage regulator (e.g., 78L05).
  • The maximum output current is 10mA. Exceeding this limit may cause the output voltage to droop or become unstable. If you need a higher output current, consider using a voltage buffer or an op-amp with a higher current capability.
  • The output voltage can be adjusted by connecting a resistor divider network between the OUT and ADJ pins. The ratio of the resistors determines the output voltage. However, be aware that adjusting the output voltage may affect the device's accuracy and stability.
