LM5145RGYR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM5145RGYR can handle?
  The LM5145RGYR can handle input voltages up to 60V, but it's recommended to keep the input voltage below 40V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in the LM5145RGYR?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output voltage is within the recommended range of 0.8V to 5.5V.
• What is the maximum output current that the LM5145RGYR can provide?
  The LM5145RGYR can provide a maximum output current of 1.5A, but it's recommended to keep the output current below 1A for optimal performance and reliability.
• How do I configure the LM5145RGYR for a specific output voltage?
  To configure the LM5145RGYR for a specific output voltage, use the feedback resistors R1 and R2 to set the output voltage. The output voltage can be calculated using the formula: Vout = 0.8V * (1 + R2/R1).
• What is the purpose of the EN pin on the LM5145RGYR?
  The EN (enable) pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
