TLV70018DDCT datasheet by Texas Instruments

TLV70018DDCT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TLV70018DDCT?
  The maximum input voltage that can be applied to the TLV70018DDCT is 18V, but it's recommended to operate within the recommended operating conditions of 2.5V to 15V for optimal performance.
• How do I ensure stability and prevent oscillations in the TLV70018DDCT?
  To ensure stability and prevent oscillations, it's essential to follow proper PCB layout guidelines, use a low-ESR capacitor at the output, and add a small capacitor (e.g., 10nF) between the VIN and GND pins to filter out noise.
• What is the minimum ESR requirement for the output capacitor?
  The minimum ESR requirement for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can cause instability and oscillations.
• Can I use the TLV70018DDCT in a high-temperature environment?
  The TLV70018DDCT is rated for operation up to 125°C, but it's essential to consider the derating of the output current and voltage regulator performance at high temperatures. Consult the datasheet for more information.
• How do I calculate the output voltage of the TLV70018DDCT?
  The output voltage of the TLV70018DDCT is adjustable and can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
