TPS720105DRVR datasheet by Texas Instruments

TPS720105DRVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS720105DRVR can handle?
  The TPS720105DRVR can handle a maximum input voltage of 12V, but it's recommended to operate within the specified input voltage range of 2.7V to 10V for optimal performance.
• How do I ensure stability and prevent oscillations in the output voltage?
  To ensure stability and prevent oscillations, it's essential to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a 10nF to 100nF ceramic capacitor between the VOUT and GND pins.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can cause instability and oscillations in the output voltage.
• Can I use the TPS720105DRVR in a high-temperature environment?
  The TPS720105DRVR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and heat dissipation in your application.
• How do I calculate the output voltage of the TPS720105DRVR?
  The output voltage of the TPS720105DRVR can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors connected between the VOUT and ADJ pins.
