LM337BT Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM337BT is 40V. Exceeding this voltage can cause damage to the device.

  • To ensure stability and prevent oscillations, a minimum output capacitance of 10uF is recommended, and the output capacitor should be located close to the output pin. Additionally, a 1uF capacitor can be added between the adjust pin and ground to improve stability.

  • The LM337BT requires a minimum load current of 3.5mA to regulate properly. If the load current is less than this, the output voltage may not be regulated accurately.

  • Yes, the LM337BT can be used as a floating regulator. However, the input voltage must be referenced to the output voltage, and the output voltage must be within the specified range.

  • The output voltage of the LM337BT can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistance between the output and adjust pins, and R2 is the resistance between the adjust pin and ground.
