TPS71525DCKRG4 datasheet by Texas Instruments

TPS71525DCKRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS71525DCKRG4?
  The maximum input voltage is 5.5V, but it's recommended to keep it below 5V to ensure reliable operation and prevent damage to the device.
• How do I ensure the output voltage is stable and accurate?
  To ensure stable and accurate output voltage, make sure to use a stable input voltage, decouple the input and output with capacitors (e.g., 1uF and 10uF), and keep the output current within the recommended range (up to 150mA).
• What is the purpose of the EN (Enable) pin, and how do I use it?
  The EN pin is used to enable or disable the regulator. Connect it to a logic high (e.g., VCC) to enable the regulator, and connect it to a logic low (e.g., GND) to disable it. This pin can be used to implement power-saving modes or to turn off the regulator when not in use.
• Can I use the TPS71525DCKRG4 in a high-temperature environment?
  The TPS71525DCKRG4 is rated for operation up to 125°C (TJ). However, it's essential to consider the thermal design and ensure proper heat dissipation to prevent overheating, especially in high-temperature environments.
• How do I calculate the output voltage of the TPS71525DCKRG4?
  The output voltage is determined by the resistor divider network (R1 and R2) connected to the FB (Feedback) pin. Use the formula: VOUT = 1.25V x (1 + R2/R1) to calculate the output voltage. Make sure to choose the correct resistor values to achieve the desired output voltage.
