TPS70851PWPR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for LDO regulators, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce noise and EMI.
  • The output voltage tolerance of the TPS70851PWPR is specified as ±2% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage. For example, for a 3.3V output, the tolerance would be ±66mV (3.3V x 0.02).
  • The maximum input voltage that can be applied to the TPS70851PWPR is 15V, but it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
  • The TPS70851PWPR has a soft-start feature that limits the inrush current during power-up. During power-down, the device will shut down quickly to prevent any damage. It's recommended to follow the power-up and power-down sequence recommended in the datasheet to ensure reliable operation.
  • The TPS70851PWPR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. It's also important to follow proper thermal design and layout guidelines to prevent overheating.
