LF247DT Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the LF247DT is 2.7V to 36V, with a maximum rating of 40V.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm is recommended. Additionally, a 1uF capacitor on the input pin is recommended to filter out noise.
  • The maximum output current of the LF247DT is 7A, but it can be limited by the thermal dissipation of the package and the PCB design.
  • The output voltage of the LF247DT can be adjusted using an external resistor divider network. The output voltage can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V) and R1 and R2 are the resistors in the divider network.
  • The enable pin (EN) is used to turn the regulator on or off. When the EN 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 modes.
