LP2981IM5-3.3/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage 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 is 3.5V, but it's recommended to keep it above 4V for optimal performance.
-
The LP2981IM5-3.3/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating.
-
Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and junction temperature to ensure the device operates within its thermal limits.
