MC79L12ACDE4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a thermal pad on the bottom of the package, connected to a copper plane on the PCB to dissipate heat. A minimum of 2oz copper thickness is recommended for the thermal plane.
  • To ensure reliable startup and shutdown, TI recommends adding a 1uF capacitor between the EN pin and GND, and a 10kΩ pull-down resistor between the EN pin and GND. This helps to prevent unwanted startup and shutdown due to noise or voltage transients.
  • Although the datasheet specifies a maximum input voltage of 15V, TI recommends limiting the input voltage to 12V to ensure reliable operation and to prevent damage to the internal circuitry.
  • The output voltage tolerance is specified as ±2% in the datasheet. To calculate the tolerance, multiply the nominal output voltage (12V) by the tolerance percentage (2%). For example, the output voltage tolerance would be ±0.24V (12V x 0.02).
  • TI recommends using a 10uF to 22uF ceramic or film capacitor with a voltage rating of at least 16V. The capacitor should be placed as close as possible to the input pin of the regulator to minimize noise and ripple.
