TPS75003RHLT datasheet by Texas Instruments

TPS75003RHLT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS75003RHLT?
  The maximum input voltage that can be applied to the TPS75003RHLT is 15V, but it's recommended to keep it below 13.2V 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, but a higher value may be required depending on the specific application.
• What is the maximum output current that the TPS75003RHLT can deliver?
  The maximum output current that the TPS75003RHLT can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
• How do I handle the thermal considerations for the TPS75003RHLT?
  To handle thermal considerations, ensure good airflow around the device, use a heat sink if necessary, and keep the junction temperature (TJ) below 125°C. The thermal resistance (θJA) of the package is 24°C/W, and the thermal resistance (θJC) of the junction-to-case is 4°C/W.
• 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 the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. Connect the EN pin to a logic-level signal or a voltage source to control the regulator's operation.
