LTC7812IUH#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LTC7812IUH can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.
  • The maximum output current that the LTC7812IUH can provide is 2A, but it's recommended to keep it below 1.5A for optimal performance and reliability.
  • To reduce the noise and ripple on the output voltage, use a low-ESR output capacitor, and add a 10nF ceramic capacitor in parallel with the output capacitor. Also, make sure to keep the input and output capacitors close to the IC.
  • The thermal shutdown temperature of the LTC7812IUH is 150°C. The IC will shut down when the junction temperature exceeds this value, and will restart when the temperature drops below 140°C.
