LM2936Z-3.3/NOPB datasheet by Texas Instruments

LM2936Z-3.3/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2936Z-3.3/NOPB can handle?
  The maximum input voltage is 26V, but it's recommended to keep it below 24V for reliable operation.
• Can I use the LM2936Z-3.3/NOPB in a high-temperature environment?
  The LM2936Z-3.3/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°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 with a low ESR (Equivalent Series Resistance) to ensure stability and accuracy. Also, ensure the input voltage is well-regulated and within the recommended range.
• Can I use the LM2936Z-3.3/NOPB in a low-dropout application?
  The LM2936Z-3.3/NOPB is not a low-dropout regulator. It requires a minimum input-to-output voltage differential of 2V to maintain regulation. For low-dropout applications, consider using a dedicated low-dropout regulator.
• How do I protect the LM2936Z-3.3/NOPB from input voltage transients?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the input from voltage transients. Ensure the TVS diode is rated for the maximum input voltage and has a response time faster than the transient duration.
