NCP1081DEG Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 25V or higher, to ensure stable operation and minimize input voltage ripple.
  • To ensure the NCP1081DEG operates within its SOA, ensure the input voltage is within the recommended range (7V to 18V), the output current is within the rated current limit (1A), and the junction temperature is below the maximum rating (150°C).
  • The EN pin is used to enable or disable the regulator. When the EN pin is pulled high (above 2.5V), the regulator is enabled, and when it's pulled low (below 0.8V), the regulator is disabled.
  • The output voltage of the NCP1081DEG can be calculated using the formula: Vout = 1.235V x (1 + R2/R1), where R1 and R2 are the resistors connected to the FB (feedback) pin.
  • The thermal resistance of the NCP1081DEG is 45°C/W (junction-to-ambient) and 10°C/W (junction-to-case).
