L78M15ABV datasheet by STMicroelectronics

L78M15ABV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78M15ABV?
  The maximum input voltage that can be applied to the L78M15ABV is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L78M15ABV is stable and doesn't oscillate?
  To ensure stability, a minimum output capacitance of 2.2uF is recommended, and the input capacitor should be at least 10uF. Additionally, the layout should be designed to minimize parasitic inductance and capacitance.
• What is the maximum output current that the L78M15ABV can provide?
  The L78M15ABV can provide up to 1.5A of output current, but it's recommended to derate the output current based on the ambient temperature and input voltage to ensure reliable operation.
• How do I protect the L78M15ABV from overheating?
  To protect the L78M15ABV from overheating, ensure good heat sinking, keep the device away from heat sources, and avoid high ambient temperatures. Also, consider adding thermal protection circuitry or using a thermal shutdown feature.
• Can I use the L78M15ABV in a switching regulator application?
  No, the L78M15ABV is a linear voltage regulator and is not suitable for switching regulator applications. It's designed for low-dropout linear regulation and should not be used in switching regulator topologies.
