TPS79501DCQ Frequently Asked Questions (FAQs)

  • The TPS79501DCQ can handle input voltages up to 6.5V, but it's recommended to keep the input voltage below 5.5V for optimal performance and to prevent damage to the device.
  • To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a value between 1uF to 10uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, the input capacitor should be placed as close to the VIN pin as possible.
  • The minimum input voltage required for the TPS79501DCQ to operate is 2.2V. However, the device can operate down to 1.7V with reduced performance and output voltage regulation.
  • The TPS79501DCQ is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
  • The output voltage of the TPS79501DCQ can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 0.8V to 5.5V.
