TPS75003RHLR datasheet by Texas Instruments

TPS75003RHLR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS75003RHLR?
  The maximum input voltage that can be applied to the TPS75003RHLR is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A minimum capacitance of 10uF is recommended.
• What is the maximum output current that the TPS75003RHLR can deliver?
  The maximum output current that the TPS75003RHLR can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
• How do I handle thermal considerations for the TPS75003RHLR?
  To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and keep the junction temperature below 125°C. Also, consider the thermal resistance of the package and the PCB layout.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the regulator. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled. Connect EN to a logic high (e.g., VCC) to enable the regulator, or connect it to a logic low (e.g., GND) to disable it.
