TPS77901DGKRG4 datasheet by Texas Instruments

TPS77901DGKRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77901DGKRG4?
  The maximum input voltage that can be applied to the TPS77901DGKRG4 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in the TPS77901DGKRG4?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a minimum capacitance of 10uF and an ESR of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.
• What is the minimum input voltage required for the TPS77901DGKRG4 to operate?
  The minimum input voltage required for the TPS77901DGKRG4 to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the TPS77901DGKRG4 in a high-temperature environment?
  The TPS77901DGKRG4 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 configure the enable pin (EN) of the TPS77901DGKRG4?
  The enable pin (EN) is an active-high input, which means it should be connected to a logic high (VCC) to enable the device. When EN is low, the device is in shutdown mode, and the output is disabled.
