LM2937ES-12 datasheet by Texas Instruments

LM2937ES-12 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2937ES-12?
  The maximum input voltage that can be applied to the LM2937ES-12 is 26V, but it's recommended to keep it below 20V for reliable operation.
• How do I ensure the output voltage is stable and within regulation?
  To ensure the output voltage is stable and within regulation, make sure to use a minimum of 10uF capacitor at the input and output pins, and keep the input voltage at least 2V above the output voltage.
• Can I use the LM2937ES-12 in a high-temperature environment?
  The LM2937ES-12 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I protect the LM2937ES-12 from input voltage transients?
  To protect the LM2937ES-12 from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input pin to limit the voltage spikes.
• Can I use the LM2937ES-12 in a parallel configuration to increase the output current?
  Yes, you can use multiple LM2937ES-12 regulators in parallel to increase the output current, but make sure to connect the outputs together and use a common input capacitor to ensure stable operation.
