UA78L09ACPK 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 that the output capacitor's ESR (Equivalent Series Resistance) is less than 5 ohms.
  • The UA78L09ACPK can handle a maximum input voltage of 35V, but it's recommended to keep the input voltage below 25V for optimal performance.
  • The UA78L09ACPK is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper heat sinking and thermal management to prevent overheating.
  • Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT, where VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current.
