UA78L12ACPKG3 Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements.
  • To ensure stability, use a minimum output capacitor of 10uF, and ensure the input capacitor is properly sized. Also, keep the input and output capacitors close to the regulator.
  • The maximum dropout voltage is 2V, which means the input voltage should be at least 2V higher than the output voltage.
  • The UA78L12ACPKG3 is rated for operation up to 125°C, but the maximum junction temperature is 150°C. Ensure proper heat sinking and thermal management to prevent overheating.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp to protect the regulator from input voltage surges and spikes.
