TPS70745PWP 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 TPS70745PWP is specified as ±2% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage (e.g., for a 3.3V output, the tolerance would be ±66mV).
  • The absolute maximum input voltage rating for the TPS70745PWP is 12V. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 10V to ensure optimal performance and reliability.
  • The TPS70745PWP is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage according to the thermal derating curves provided in the datasheet.
  • To ensure stability, follow the recommended output capacitor selection guidelines in the datasheet, and use a capacitor with a low equivalent series resistance (ESR). Additionally, ensure that the input capacitor is properly sized and placed close to the device.
