LP2951CMX Frequently Asked Questions (FAQ)
-
The LP2951CMX can handle input voltages up to 30V, but it's recommended to keep the input voltage below 20V for optimal performance and to prevent overheating.
-
The output voltage of the LP2951CMX can be adjusted by connecting a resistor divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage.
-
The LP2951CMX requires a minimum input voltage of 7V to operate, but it's recommended to keep the input voltage above 8V for optimal performance.
-
The LP2951CMX is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for optimal performance and reliability.
-
To protect the LP2951CMX from input voltage transients, it's recommended to add a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input pin.
