LP38690DT-3.3/NOPB Frequently Asked Questions (FAQ)

  • The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 6.3V or higher, to ensure stable operation and minimize output voltage ripple.

  • To ensure accurate and stable output voltage, use a high-precision resistor divider network for the feedback resistors (R1 and R2), and ensure the output capacitor (Cout) is a low-ESR type with a value of 10uF to 22uF.

  • The maximum input voltage that can be applied to the LP38690DT-3.3/NOPB is 15V, but it's recommended to keep the input voltage below 12V for optimal performance and reliability.

  • To protect the device from overheating, ensure good thermal conduction by using a heat sink or a thermally conductive PCB, and avoid operating the device at maximum power dissipation for extended periods.

  • The LP38690DT-3.3/NOPB is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal management and derate the output current accordingly.
