The maximum input voltage that can be applied to the LP3874EMP-3.3 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the distance between the input and output pins.
The minimum input voltage required for the LP3874EMP-3.3 to operate is 2.5V, but it's recommended to keep it above 3V for optimal performance and to ensure the output voltage is within the specified tolerance.
The LP3874EMP-3.3 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to prevent overheating and ensure reliable operation.
The output voltage tolerance of the LP3874EMP-3.3 is typically ±2% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage (3.3V) by the tolerance percentage (±2%).
