REF02BU/2K5E4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with the REF02BU/2K5E4 at the center, and decoupling capacitors placed close to the device. A solid ground plane and minimal trace lengths can also help reduce noise and improve performance.
  • The REF02BU/2K5E4 has a thermal pad that must be connected to a thermal relief pattern on the PCB to ensure proper heat dissipation. A thermal via or a copper pour connected to a ground plane can be used to dissipate heat. Additionally, ensure that the device is not exposed to high temperatures during soldering or rework.
  • Although the datasheet specifies a minimum input voltage of 4.5V, it's recommended to operate the REF02BU/2K5E4 with an input voltage between 5V and 18V to ensure optimal performance and stability.
  • A 0.1uF ceramic capacitor should be placed between the VIN pin and GND, and a 10uF tantalum capacitor should be placed between the VOUT pin and GND. These capacitors help to filter out noise and ensure stable operation.
  • The typical output noise of the REF02BU/2K5E4 is around 10uVpp (peak-to-peak) in the 0.1Hz to 10Hz frequency range. However, this can vary depending on the input voltage, operating temperature, and PCB layout.
