LM78M15CT/NOPB datasheet by Texas Instruments

LM78M15CT/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM78M15CT/NOPB can handle?
  The maximum input voltage is 35V, but it's recommended to keep it below 25V for reliable operation.
• Can I use the LM78M15CT/NOPB in a high-temperature environment?
  The LM78M15CT/NOPB is rated for operation up to 125°C, but thermal derating is required above 50°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  Use a 10uF or larger output capacitor to ensure stability and accuracy. Additionally, keep the input and output capacitors close to the regulator to minimize noise and oscillation.
• Can I use the LM78M15CT/NOPB in a switching power supply application?
  No, the LM78M15CT/NOPB is a linear regulator and not suitable for switching power supply applications. It's designed for low-dropout, low-noise, and high-reliability applications.
• What is the minimum input voltage required for the LM78M15CT/NOPB to function properly?
  The minimum input voltage is 7.5V, but it's recommended to keep it above 10V for reliable operation and to ensure the output voltage is within regulation.
