LP2981AIM5-3.0/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LP2981 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.

  • The minimum input voltage required for the LP2981 to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance.

  • The LP2981 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability. Use a heat sink or thermal pad to dissipate heat if necessary.

  • The output voltage of the LP2981 is fixed at 3.0V, but it can be adjusted using an external resistor divider network. Use the formula: Vout = 3.0V * (1 + R1/R2) to calculate the output voltage.
