NCP1421DMR2G Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
  • Ensure the input voltage is within the recommended range of 2.7V to 5.5V, and the output current does not exceed the maximum rating of 1A.
  • The EN (Enable) pin is used to enable or disable the regulator. Connect EN to VIN to enable the regulator, or connect EN to GND to disable it.
  • The output voltage is determined by the resistor divider network connected to the FB (Feedback) pin. Use the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The thermal shutdown temperature is typically 150°C, with a hysteresis of 10°C.
