Overview

The NCV4274C is a precision micro-power voltage regulator with an output current capability of 400 mA available in the DPAK package.The output voltage is accurate within ±2.0% with a maximum dropout voltage of 0.5 V with an input up to 40 V. Low quiescent current is a feature drawing only 130 µA with a 1 mA load. This part is ideal for automotive and all battery operated microprocessor equipment.The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments.

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.)
