BU4227F-TR Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the BU4227F-TR is -40°C to 85°C.
  • To ensure the stability of the output voltage, it is recommended to use a ceramic capacitor with a capacitance value of 1uF or more, and an ESR of 1Ω or less, between the VOUT pin and the GND pin.
  • The maximum input voltage that the BU4227F-TR can handle is 18V. Exceeding this voltage may cause damage to the device.
  • The output voltage of the BU4227F-TR can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors connected between the VOUT pin, the ADJ pin, and the GND pin.
  • The quiescent current of the BU4227F-TR is typically around 1.5mA, but it can vary depending on the input voltage and output load conditions.
