L78L08ACD13TR datasheet by STMicroelectronics

L78L08ACD13TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78L08ACD13TR?
  The maximum input voltage is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L78L08ACD13TR is stable and doesn't oscillate?
  To ensure stability, add a 10uF capacitor between the input and ground, and a 10uF capacitor between the output and ground. Also, keep the input and output capacitors close to the regulator.
• What is the minimum input voltage required for the L78L08ACD13TR to function properly?
  The minimum input voltage is 10V, but it's recommended to keep it above 12V for reliable operation.
• Can I use the L78L08ACD13TR in a high-temperature environment?
  The L78L08ACD13TR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermally-enhanced package for high-temperature applications.
• How do I protect the L78L08ACD13TR from input voltage surges?
  Add a TVS (Transient Voltage Suppressor) diode or a zener diode between the input and ground to protect the regulator from voltage surges.
