L7986TR Frequently Asked Questions (FAQ)

  • The L7986TR can handle a maximum input voltage of 30V, but it's recommended to keep it below 28V for reliable operation.

  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 10nF capacitor between the VIN and EN pins.

  • The L7986TR can operate with an input voltage as low as 7V, but the output voltage regulation may not be guaranteed below 8V.

  • The L7986TR is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage to ensure reliable operation above 125°C.

  • The output voltage of the L7986TR is adjustable and can be calculated using the formula: Vout = 1.25 x (1 + R2/R1), where R1 and R2 are the resistors connected to the FB pin.
