TPS77118DGK datasheet by Texas Instruments

TPS77118DGK Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77118DGK?
  The maximum input voltage that can be applied to the TPS77118DGK is 15V, but it's recommended to keep it below 13.2V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a minimum capacitance of 2.2uF and an ESR of less than 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the minimum input voltage required for the TPS77118DGK to operate?
  The minimum input voltage required for the TPS77118DGK to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS77118DGK in a high-temperature environment?
  The TPS77118DGK is rated for operation up to 125°C, but it's essential to ensure that the device is properly heatsinked and the thermal design is adequate to prevent overheating.
• How do I calculate the output voltage of the TPS77118DGK?
  The output voltage of the TPS77118DGK can be calculated using the formula: Vout = 1.221V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
