TPS76818QD datasheet by Texas Instruments

TPS76818QD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS76818QD?
  The maximum input voltage that can be applied to the TPS76818QD is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a capacitor with a value of at least 2.2uF and an ESR of less than 1 ohm between the output and ground. Additionally, the input capacitor should have a value of at least 1uF and an ESR of less than 1 ohm.
• What is the minimum input voltage required for the TPS76818QD to function properly?
  The minimum input voltage required for the TPS76818QD to function properly is 2.7V. However, the device can operate down to 2.2V, but with reduced performance and accuracy.
• Can I use the TPS76818QD in a high-temperature environment?
  The TPS76818QD is rated for operation up to 125°C, but it's essential to ensure proper thermal management to prevent overheating. A heat sink or a thermal pad can be used to improve heat dissipation.
• How do I calculate the output voltage of the TPS76818QD?
  The output voltage of the TPS76818QD can be calculated using the formula: Vout = 1.184V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
