Overview

The NCP146 is 300 mA LDO that provides the engineer with a verystable, accurate voltage with low noise suitable for space constrained,noise sensitive applications. In order to optimize performance forbattery operated portable applications, the NCP146 employs thedynamic quiescent current adjustment for very low IQ consumption atno−load.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
