TLV3401IDR datasheet by Texas Instruments

TLV3401IDR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TLV3401IDR can handle?
  The TLV3401IDR can handle input voltages up to 36V, but it's recommended to keep the input voltage below 30V for optimal performance and to prevent damage to the device.
• How do I ensure the TLV3401IDR is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input and output pins with capacitors, and use a minimum of 10nF capacitor between the VIN and GND pins. Also, keep the layout clean and avoid long traces to minimize noise and parasitic inductance.
• What is the minimum input voltage required for the TLV3401IDR to operate?
  The TLV3401IDR can operate with input voltages as low as 2.7V, but the output voltage regulation may not be accurate below 3.5V. For optimal performance, it's recommended to use an input voltage of at least 4V.
• Can I use the TLV3401IDR in a high-temperature environment?
  The TLV3401IDR is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TLV3401IDR?
  The output voltage of the TLV3401IDR is determined by the resistor divider network connected to the FB pin. Use the formula: VOUT = 1.24V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
