LP3961EMP-1.8/NOPB datasheet by Texas Instruments

LP3961EMP-1.8/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3961EMP-1.8/NOPB?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the LP3961EMP-1.8/NOPB is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the LP3961EMP-1.8/NOPB to operate?
  The minimum input voltage is 2.5V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the LP3961EMP-1.8/NOPB in a high-temperature environment?
  The LP3961EMP-1.8/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to prevent overheating and ensure reliability.
• How do I calculate the output voltage of the LP3961EMP-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.
