LM25018MR/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 = (R1 / R2) * (1 + R2 / R3) * Vref, where R1, R2, and R3 are the resistors in the feedback network, and Vref is the internal reference voltage (1.2V).
  • 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. You can also use an external signal to control the EN pin.
