LP3855EMP-2.5/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 7V, but it's recommended to keep it below 6V for reliable operation.

  • To ensure accurate and stable output voltage, make sure to use a high-quality output capacitor with low ESR, and follow the recommended PCB layout guidelines to minimize noise and parasitic inductance.

  • Yes, the LP3855EMP-2.5/NOPB is rated for operation up to 125°C, but the output current may need to be derated at higher temperatures to prevent overheating.

  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the device from voltage transients and spikes.

  • Yes, the LP3855EMP-2.5/NOPB has a low dropout voltage of 0.5V, making it suitable for low-dropout applications, but ensure the input voltage is within the recommended range.
