LM2940CT-9.0/NOPB datasheet by Texas Instruments

LM2940CT-9.0/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2940CT-9.0/NOPB?
  The maximum input voltage that can be applied to the LM2940CT-9.0/NOPB is 26V. Exceeding this voltage can cause damage to the device.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum of 10uF capacitor at the input and output pins, and to keep the input and output capacitors as close to the device as possible.
• What is the minimum input voltage required for the LM2940CT-9.0/NOPB to operate?
  The minimum input voltage required for the LM2940CT-9.0/NOPB to operate is 11V. The device will not regulate the output voltage if the input voltage is below this threshold.
• Can I use the LM2940CT-9.0/NOPB in a high-temperature environment?
  The LM2940CT-9.0/NOPB is rated for operation up to 125°C. However, it is recommended to derate the output current and input voltage to ensure reliable operation in high-temperature environments.
• How do I protect the LM2940CT-9.0/NOPB from input voltage transients?
  To protect the LM2940CT-9.0/NOPB from input voltage transients, it is recommended to use a transient voltage suppressor (TVS) diode or a voltage clamp at the input pin.
