The maximum input voltage that can be applied to the LP3981IMM-3.3/NOPB is 15V. Exceeding this voltage may damage the device.
To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 2.2uF and a maximum ESR of 1.5 ohms. Additionally, the input capacitor should be at least 1uF with an ESR of 1 ohm or less.
The minimum input voltage required for the LP3981IMM-3.3/NOPB to operate is 3.5V. Operating the device below this voltage may affect its performance and stability.
The LP3981IMM-3.3/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the device's output current and voltage according to the temperature derating curve in the datasheet.
The power dissipation of the LP3981IMM-3.3/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout. Where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
