LM5109AMAX/NOPB datasheet by Texas Instruments

LM5109AMAX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM5109AMAX/NOPB?
  The maximum operating temperature range for the LM5109AMAX/NOPB is -40°C to 125°C.
• How do I ensure the stability of the output voltage in the LM5109AMAX/NOPB?
  To ensure stability, a minimum output capacitance of 10uF with an ESR of 1Ω or less is recommended. Additionally, the output voltage should be decoupled with a 10nF ceramic capacitor.
• What is the maximum input voltage that the LM5109AMAX/NOPB can handle?
  The maximum input voltage that the LM5109AMAX/NOPB can handle is 42V.
• How do I calculate the output voltage of the LM5109AMAX/NOPB?
  The output voltage of the LM5109AMAX/NOPB can be calculated using the formula: Vout = (R1/R2) * (1 + R3/R4) * Vref, where R1, R2, R3, and R4 are the resistors in the feedback network, and Vref is the internal reference voltage.
• What is the purpose of the EN pin on the LM5109AMAX/NOPB?
  The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is disabled, and when it is pulled high, the regulator is enabled.
