LM337TG Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM337TG is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure stability of the output voltage, a minimum output capacitance of 10uF is recommended. Additionally, the output capacitor should have a low equivalent series resistance (ESR) to prevent oscillations.
  • The maximum output current that the LM337TG can provide is 1.5A. Exceeding this current can cause overheating and damage to the device.
  • The output voltage of the LM337TG can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage can be calculated using the formula: Vout = 1.25 x (1 + R2/R1).
  • The thermal shutdown temperature of the LM337TG is typically around 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
