LM25148RGYR Frequently Asked Questions (FAQs)

  • The LM25148RGYR can handle a maximum input voltage of 42V, but it's recommended to operate it within the specified input voltage range of 4.5V to 36V for optimal performance.
  • To ensure the stability of the output voltage, it's essential to use the recommended output capacitor value and type, as specified in the datasheet. Additionally, the input capacitor should be placed close to the VIN pin to minimize noise and ensure stability.
  • The LM25148RGYR can provide a maximum output current of 2A, but it's recommended to operate it within the specified output current range of 0.5A to 1.5A for optimal performance and thermal management.
  • The soft-start feature of the LM25148RGYR can be configured by connecting a capacitor between the SS pin and GND. The value of the capacitor determines the soft-start time, with a larger capacitor value resulting in a longer soft-start time.
  • The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power sequencing or to shut down the regulator when not in use.
