LP38690DT-5.0/NOPB datasheet by Texas Instruments

LP38690DT-5.0/NOPB Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the LP38690DT-5.0/NOPB?
  The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
• How do I ensure stability in the LP38690DT-5.0/NOPB voltage regulator?
  To ensure stability, use a minimum output capacitor of 10uF, and ensure that the output capacitor's ESR (Equivalent Series Resistance) is less than 1 ohm.
• What is the maximum input voltage that the LP38690DT-5.0/NOPB can handle?
  The maximum input voltage that the LP38690DT-5.0/NOPB can handle is 15V, but it's recommended to keep the input voltage below 12V for optimal performance.
• Can I use the LP38690DT-5.0/NOPB in a high-temperature environment?
  The LP38690DT-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
• How do I calculate the power dissipation of the LP38690DT-5.0/NOPB?
  The power dissipation of the LP38690DT-5.0/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
