LM3544MX-L/NOPB datasheet by Texas Instruments

LM3544MX-L/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3544MX-L/NOPB?
  The maximum input voltage that can be applied to the LM3544MX-L/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage in the LM3544MX-L/NOPB?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the maximum output current that the LM3544MX-L/NOPB can deliver?
  The maximum output current that the LM3544MX-L/NOPB can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
• How do I calculate the output voltage of the LM3544MX-L/NOPB?
  The output voltage of the LM3544MX-L/NOPB can be calculated using the formula: Vout = (R1 / R2) * (1.24V), where R1 and R2 are the resistors connected to the feedback pin.
• What is the purpose of the enable pin (EN) in the LM3544MX-L/NOPB?
  The enable pin (EN) is used to turn the regulator on or off. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
