LP2951ACM/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LP2951ACM is 30V, but it's recommended to keep it below 24V for reliable operation.

  • 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).

  • The LP2951ACM can regulate the output voltage down to an input voltage of around 6.5V, but it's recommended to keep the input voltage above 7V for reliable operation.

  • The LP2951ACM 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 ensure reliable operation.

  • The output voltage of the LP2951ACM can be calculated using the formula: Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors used in the output voltage divider.
