LP3985IM5-5.0/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LP3985IM5-5.0/NOPB is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
-
To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 2.2uF and a maximum ESR of 1 ohm. Additionally, the input capacitance should be at least 1uF.
-
The dropout voltage of the LP3985IM5-5.0/NOPB is typically around 300mV at an output current of 500mA. This means that the input voltage must be at least 300mV higher than the output voltage to maintain regulation.
-
The LP3985IM5-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to prevent overheating. It's also important to ensure good thermal design and heat sinking to keep the junction temperature below 125°C.
-
The power dissipation of the LP3985IM5-5.0/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.
