TPS2080D datasheet by Texas Instruments

TPS2080D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS2080D can handle?
  The TPS2080D can handle input voltages up to 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation.
• How do I ensure that the TPS2080D is properly powered on and off?
  To ensure proper power-on and power-off, make sure to follow the recommended power-up and power-down sequencing in the datasheet, and use a capacitor on the EN pin to filter out noise and ensure a clean enable signal.
• What is the minimum load current required for the TPS2080D to operate properly?
  The TPS2080D can operate with a minimum load current of 1mA, but it's recommended to have a minimum load current of 10mA to ensure stable operation.
• How do I calculate the output voltage of the TPS2080D?
  The output voltage of the TPS2080D can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the internal reference voltage (1.2V).
• What is the purpose of the EN pin on the TPS2080D?
  The EN (enable) pin is used to turn the regulator on and off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
