TPS990STPZPRQ1 Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the TPS990STPZPRQ1 datasheet (page 23) and in the 'TPS990STPZPRQ1 Thermal Layout Guidelines' application note (SLVAE45). It's essential to follow these guidelines to ensure optimal thermal performance and prevent overheating.
The input capacitor selection depends on the input voltage, output voltage, and output current. TI recommends using a low-ESR ceramic capacitor with a value between 4.7 μF and 10 μF. A higher capacitance value can help reduce input voltage ripple, but may increase the startup time. Refer to the 'TPS990STPZPRQ1 Input Capacitor Selection' application note (SLVAE46) for more information.
The TPS990STPZPRQ1 has a maximum output current rating of 1 A. However, the actual output current capability depends on the input voltage, output voltage, and ambient temperature. Be sure to check the device's thermal performance and power dissipation to ensure reliable operation within the specified limits.
The TPS990STPZPRQ1 has an operating junction temperature range of -40°C to 150°C. While it can operate in high-temperature environments, the device's performance and reliability may degrade above 125°C. Be sure to check the thermal design and heat sinking to ensure the device operates within the specified temperature range.
To ensure accurate and stable output voltage, follow the recommended PCB layout, use a high-quality output capacitor, and minimize noise and ripple on the input voltage. Additionally, consider using a voltage reference IC, such as the TLV7031, to improve output voltage accuracy and stability.
