The minimum input voltage required for the LP2950CDT-3.3 to operate is 3.5V, but it's recommended to use a minimum of 4V to ensure stable operation.
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 short traces to minimize inductance.
The LP2950CDT-3.3 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to derate the output current and voltage according to the temperature derating curve in the datasheet.
The output voltage tolerance of the LP2950CDT-3.3 is ±2% over the entire operating temperature range. You can calculate the output voltage tolerance by multiplying the nominal output voltage (3.3V) by the tolerance percentage (±2%).
The LP2950CDT-3.3 has a relatively high dropout voltage of 1.5V, so it's not suitable for low-dropout applications. If you need a low-dropout regulator, consider using a different device with a lower dropout voltage.
