TPS28225DRBR datasheet by Texas Instruments

TPS28225DRBR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS28225DRBR can handle?
  The TPS28225DRBR can handle input voltages up to 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  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.
• What is the maximum output current that the TPS28225DRBR can provide?
  The TPS28225DRBR can provide up to 2A of output current, but it's recommended to keep it below 1.5A for optimal performance and to prevent overheating.
• How do I adjust the output voltage?
  The output voltage can be adjusted by using a resistive 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 output voltage.
• What is the purpose of the EN pin, and how do I use it?
  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-saving features or to turn the regulator on and off as needed.
