L4979DTR-E Frequently Asked Questions (FAQs)

  • The L4979DTR-E can handle a maximum input voltage of 40V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a minimum ESR of 0.1 ohms. Also, keep the input and output capacitors close to the IC and use a good quality PCB layout.
  • The L4979DTR-E can deliver a maximum output current of 1.5A, but it's recommended to keep it below 1A for reliable operation and to prevent overheating.
  • The output voltage of the L4979DTR-E can be adjusted by using a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.25 x (1 + R1/R2).
  • The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
