LM34919BTL/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (1.2V to 15V).
  • The maximum output current is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
  • The EN (enable) pin is used to turn the regulator on or off. Connect it to VIN to enable the regulator, or to GND to disable it.
