LM3405AXMY/NOPB datasheet by Texas Instruments

LM3405AXMY/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM3405AXMY/NOPB can handle?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 1.2V to 15V.
• What is the maximum output current that the LM3405AXMY/NOPB can provide?
  The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I calculate the output voltage of the LM3405AXMY/NOPB?
  The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
• What is the purpose of the EN pin on the LM3405AXMY/NOPB?
  The EN (Enable) pin is used to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled.
