LP2951CNG Frequently Asked Questions (FAQ)

  • The LP2951CNG can handle input voltages up to 30V, but it's recommended to keep the input voltage below 24V for optimal performance and to prevent overheating.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output capacitor's ESR (Equivalent Series Resistance) below 1 ohm. Also, avoid using ceramic capacitors with high ESL (Equivalent Series Inductance) as they can cause oscillations.

  • The LP2951CNG requires a minimum input voltage of 7V to regulate properly. If the input voltage drops below 7V, the output voltage may not be regulated and may drop below the nominal value.

  • The LP2951CNG is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation.

  • The output voltage of the LP2951CNG can be calculated using the formula: Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors used in the voltage divider network. Make sure to choose the correct resistor values to achieve the desired output voltage.
