LTC6953IUKG#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC6953 involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing the decoupling capacitors close to the device. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines. Also, ensure that the output capacitor is properly sized and placed close to the device. Additionally, a small series resistor (e.g., 10Ω) can be added to the output to improve stability.
  • The maximum output current of the LTC6953 is 20mA. However, it's recommended to limit the output current to 10mA or less to ensure reliable operation and minimize thermal issues.
  • While the LTC6953 can be used as a voltage regulator, it's not its primary function. The device is designed as a low-noise, low-dropout voltage reference, and its output voltage is not adjustable. If you need a voltage regulator, consider using a dedicated voltage regulator IC.
  • The output voltage of the LTC6953 is fixed at 2.5V, and it's not adjustable. The device is designed to provide a stable, low-noise 2.5V reference voltage.
