L79L05ACZ datasheet by STMicroelectronics

L79L05ACZ Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L79L05ACZ can handle?
  The maximum input voltage for the L79L05ACZ is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 2.2uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 5 ohms.
• What is the dropout voltage of the L79L05ACZ?
  The dropout voltage of the L79L05ACZ is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
• Can I use the L79L05ACZ in a high-temperature environment?
  The L79L05ACZ is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.
• How do I protect the L79L05ACZ from input voltage surges?
  A TVS (Transient Voltage Suppressor) diode or a varistor can be used to protect the L79L05ACZ from input voltage surges and spikes.
