LTC3445EUF#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the VIN pin is 5.5V, as specified in the Absolute Maximum Ratings section of the datasheet. Exceeding this voltage can damage the device.

  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, as specified in the datasheet. Additionally, the output voltage should be decoupled from the input voltage using a 1uF or larger capacitor.

  • The RUN pin is an active-high enable input that allows the user to turn the regulator on and off. When the RUN pin is high, the regulator is enabled, and when it is low, the regulator is disabled. This pin can be used to implement power sequencing or to reduce power consumption in standby mode.

  • The output voltage of the LTC3445EUF can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The datasheet provides a detailed explanation of how to use this formula to set the output voltage.

  • The maximum output current that the LTC3445EUF can deliver is 500mA, as specified in the datasheet. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
