UCR03EWPFSR027 Frequently Asked Questions (FAQs)

  • ROHM recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer, and multiple vias to dissipate heat efficiently.
  • Use a heat sink, ensure good airflow, and consider derating the output current according to the temperature derating curve provided in the datasheet.
  • The maximum allowed voltage on the enable pin (EN) is 6V, as specified in the datasheet. Exceeding this voltage may damage the device.
  • Yes, the UCR03EWPFSR027 is suitable for battery-powered devices due to its low quiescent current (IQ) and high efficiency. However, consider the battery's voltage range and the regulator's dropout voltage when designing your system.
  • The output voltage tolerance is typically ±2% of the nominal output voltage. To calculate the tolerance, multiply the nominal output voltage by the tolerance percentage (e.g., 3.3V x 0.02 = ±0.066V).
