LM337D2TG Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM337D2TG is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure a stable output voltage, make sure to use a minimum of 10uF capacitor at the output and a minimum of 0.1uF capacitor at the input. Also, ensure that the input voltage is at least 2V higher than the desired output voltage.
  • The maximum current that the LM337D2TG can supply is 1.5A. However, it's recommended to derate the current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The output voltage of the LM337D2TG can be adjusted by using a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula: Vout = 1.25V * (1 + R1/R2).
  • The thermal shutdown temperature of the LM337D2TG is typically around 150°C. When the junction temperature exceeds this value, the device will shut down to prevent damage.
