L7986TA Frequently Asked Questions (FAQ)

  • The L7986TA 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 use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the IC and use a good quality PCB layout.

  • The L7986TA can operate with an input voltage as low as 7V, but the output voltage regulation may not be guaranteed below 8V.

  • The L7986TA is rated for operation up to 150°C, but the maximum junction temperature should not exceed 125°C for reliable operation. Make sure to provide adequate heat sinking and thermal management.

  • The output voltage of the L7986TA can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.25V), and R1 and R2 are the resistors in the feedback network.
