XCL221B121ER-G Frequently Asked Questions (FAQs)

  • Torex recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended for the thermal pad.
  • To ensure stable output voltage, it's recommended to use a capacitor with a low ESR (Equivalent Series Resistance) value, such as a ceramic capacitor, and to follow the recommended input capacitor selection guidelines in the datasheet.
  • The maximum allowable ripple voltage on the input capacitor is 10% of the input voltage. Exceeding this value may affect the regulator's stability and performance.
  • The XCL221B121ER-G is rated for operation up to 105°C. However, it's recommended to derate the output current and consider thermal management measures to ensure reliable operation in high-temperature environments.
  • It's recommended to use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to protect the regulator from input voltage surges or spikes.
