KDZVTR3.0B - ROHM Semiconductor

KDZVTR3.0B Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the KDZVTR3.0B?
  A good PCB layout for the KDZVTR3.0B involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the stability of the output voltage in the KDZVTR3.0B?
  To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor has a low ESR (Equivalent Series Resistance). Additionally, use a 1uF ceramic capacitor for decoupling between the VIN and GND pins.
• What is the maximum input voltage that the KDZVTR3.0B can handle?
  The KDZVTR3.0B can handle a maximum input voltage of 36V, but it's recommended to operate within the specified input voltage range of 3.0V to 18V for optimal performance and reliability.
• How do I calculate the output voltage of the KDZVTR3.0B?
  The output voltage of the KDZVTR3.0B can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
• What is the thermal derating curve for the KDZVTR3.0B?
  The thermal derating curve for the KDZVTR3.0B is not explicitly stated in the datasheet, but it's recommended to follow the general guidelines for thermal derating in the ROHM Semiconductor application notes.
