L78M24CDT datasheet by STMicroelectronics

L78M24CDT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78M24CDT?
  The maximum input voltage that can be applied to the L78M24CDT is 35V, although the recommended maximum input voltage is 30V for reliable operation.
• How do I ensure the L78M24CDT is stable and doesn't oscillate?
  To ensure stability, a minimum output capacitance of 2.2uF is recommended, and the output capacitor should be placed as close as possible to the output pin. Additionally, a 0.1uF capacitor between the input and ground can help to filter out noise.
• What is the maximum output current that the L78M24CDT can deliver?
  The maximum output current that the L78M24CDT can deliver is 500mA, although the recommended maximum output current is 300mA for reliable operation.
• How do I protect the L78M24CDT from overheating?
  To protect the L78M24CDT from overheating, ensure that the device is mounted on a suitable heat sink, and that the ambient temperature is within the recommended operating range. Additionally, reduce the output current or input voltage to reduce power dissipation.
• Can I use the L78M24CDT in a switching regulator application?
  No, the L78M24CDT is a linear voltage regulator and is not suitable for use in switching regulator applications. It is designed to provide a stable output voltage in linear mode only.
