LM5109AMA/NOPB datasheet by Texas Instruments

LM5109AMA/NOPB Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM5109AMA/NOPB?
  The maximum operating temperature range for the LM5109AMA/NOPB is -40°C to 125°C.
• How do I ensure the stability of the output voltage in the LM5109AMA/NOPB?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled from the input voltage using a capacitor with a value of at least 1uF.
• What is the maximum input voltage that the LM5109AMA/NOPB can handle?
  The maximum input voltage that the LM5109AMA/NOPB can handle is 42V.
• How do I calculate the output voltage of the LM5109AMA/NOPB?
  The output voltage of the LM5109AMA/NOPB can be calculated using the following formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors used in the feedback network, Vin is the input voltage, and Vref is the reference voltage (typically 1.2V).
• What is the typical quiescent current of the LM5109AMA/NOPB?
  The typical quiescent current of the LM5109AMA/NOPB is 2.5mA.
