LM334D Frequently Asked Questions (FAQs)

  • The LM334D can operate from -40°C to 125°C, but the output voltage accuracy is only guaranteed from -20°C to 85°C.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be placed as close to the output pin as possible. Additionally, the input capacitor should be at least 1uF.
  • The minimum input voltage required for the LM334D to function properly is 3.5V, but it's recommended to use a minimum of 4V to ensure proper regulation.
  • Yes, the LM334D can be used as a current source. The output current is determined by the resistor connected between the ADJ pin and the output pin. The current is calculated as Iout = 1.2V / R, where R is the resistance in ohms.
  • The output voltage of the LM334D can be adjusted by connecting a resistor divider network between the output pin and the ADJ pin. The output voltage is calculated as Vout = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
