TPS7B91050DBVR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good thermal design practices, such as using a solid ground plane, placing thermal vias under the device, and keeping the thermal path short and direct.
  • To ensure stability, it's crucial to follow the recommended capacitor selection and placement guidelines in the datasheet. Additionally, ensure that the output capacitor has a low equivalent series resistance (ESR) and is placed close to the output pin. You can also add a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
  • The output voltage accuracy and tolerance can be calculated by considering the internal reference voltage tolerance, resistor tolerance, and temperature coefficient. You can use the formulas provided in the datasheet to calculate the output voltage accuracy and tolerance.
  • The recommended input capacitor value is 1μF to 10μF, and it's recommended to use a low-ESR ceramic capacitor (e.g., X5R or X7R) to minimize input voltage ripple and ensure stable operation.
