LP3966ES-1.8/NOPB datasheet by Texas Instruments

LP3966ES-1.8/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3966ES-1.8/NOPB?
  The maximum input voltage is 7V, but it's recommended to keep it below 6V to ensure reliable operation.
• How do I ensure the LP3966ES-1.8/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output voltage within the recommended range. Also, avoid using long output cables and minimize the PCB trace inductance.
• What is the minimum input capacitance required for the LP3966ES-1.8/NOPB?
  The minimum input capacitance required is 1uF, but it's recommended to use a 2.2uF or larger capacitor to ensure stable operation.
• Can I use the LP3966ES-1.8/NOPB in a high-temperature environment?
  The LP3966ES-1.8/NOPB is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. Ensure proper thermal design and heat sinking to maintain reliable operation.
• How do I calculate the output voltage of the LP3966ES-1.8/NOPB?
  The output voltage is fixed at 1.8V, but you can adjust it by using an external resistor divider network. Refer to the datasheet for the calculation formula and example circuits.
