LP2951CMX-3.0/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LP2951CMX-3.0/NOPB is 30V. Exceeding this voltage can cause damage to the device.

  • To ensure stability of the output voltage, a minimum output capacitance of 10uF is recommended. Additionally, the output capacitor should have an ESR (Equivalent Series Resistance) of less than 1 ohm.

  • The maximum output current that the LP2951CMX-3.0/NOPB can provide is 50mA. Exceeding this current can cause the device to overheat or fail.

  • The output voltage of the LP2951CMX-3.0/NOPB can be adjusted by connecting a resistor divider network between the output pin and the adjust pin. The output voltage can be calculated using the formula: Vout = 3.0V x (1 + R1/R2).

  • The quiescent current of the LP2951CMX-3.0/NOPB is typically around 5mA. This is the current consumed by the device when there is no load connected.
