TPS74901KTWT Frequently Asked Questions (FAQs)

  • The TPS74901KTWT can handle input voltages up to 15V, but it's recommended to keep the input voltage below 13.2V for optimal performance and to prevent overheating.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and the output capacitor should be placed as close to the output pin as possible. Additionally, the input capacitor should be at least 1uF and placed close to the input pin.
  • The TPS74901KTWT can provide up to 1A of output current, but it's recommended to keep the output current below 0.8A for optimal performance and to prevent overheating.
  • The output voltage can be adjusted by using a resistor divider network between the output pin and the ground pin. The ratio of the resistors determines the output voltage, and the datasheet provides a formula to calculate the required resistor values.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
