TPS3823-33DBVTG4 datasheet by Texas Instruments

TPS3823-33DBVTG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3823-33DBVTG4?
  The recommended layout and placement for the TPS3823-33DBVTG4 involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note 'TPS3823 Layout and Placement Guidelines' for more information.
• How do I ensure the TPS3823-33DBVTG4 is stable and does not oscillate?
  To ensure stability, follow the recommended layout and placement guidelines, use a minimum of 1uF ceramic capacitor at the input and output, and ensure the output capacitor has a low ESR. Additionally, the device has a built-in compensation network, so no external compensation is required.
• What is the maximum input voltage that the TPS3823-33DBVTG4 can handle?
  The TPS3823-33DBVTG4 can handle a maximum input voltage of 6V, but it is recommended to operate within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
• Can I use the TPS3823-33DBVTG4 in a high-temperature environment?
  The TPS3823-33DBVTG4 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to operate the device within the specified temperature range of -40°C to 125°C for optimal performance and reliability.
• How do I calculate the output voltage of the TPS3823-33DBVTG4?
  The output voltage of the TPS3823-33DBVTG4 is fixed at 3.3V and is not adjustable. The device is designed to provide a stable 3.3V output voltage with a ±2% tolerance.
