L78M05ABDT-TR datasheet by STMicroelectronics

L78M05ABDT-TR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78M05ABDT-TR?
  The maximum input voltage that can be applied to the L78M05ABDT-TR is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L78M05ABDT-TR is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output.
• What is the minimum input voltage required for the L78M05ABDT-TR to function properly?
  The minimum input voltage required for the L78M05ABDT-TR to function properly is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the L78M05ABDT-TR in a high-temperature environment?
  The L78M05ABDT-TR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I protect the L78M05ABDT-TR from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the L78M05ABDT-TR from input voltage transients.
