TL3845BD Frequently Asked Questions (FAQs)

  • The TL3845BD can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the capacitor's ESR (Equivalent Series Resistance) is less than 1 ohm. Also, place the capacitor close to the output pin and use a low-ESR capacitor.
  • The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 1.5 times the input voltage. A larger capacitor can help reduce input ripple and improve noise rejection.
  • While the TL3845BD can handle high currents, it's not recommended for high-current applications (>1A) due to thermal limitations. For high-current applications, consider using a more suitable regulator or adding external current limiting and thermal protection.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
