NCV4274C
Regulator, 400 mA,
Low Dropout Voltage
Description
The NCV4274C is a precision micro−power voltage regulator with
an output current capability of 400 mA available in the DPAK,
D2PAK and SOT−223 packages.
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 125
mA
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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Load Dump Test B (with centralized load dump suppression) according to ISO16750-2 standard. Guaranteed by design. Not tested in
production. Passed Class C.
2. This device series incorporates ESD protection and is tested by the following methods:
ESD HBM tested per AEC−Q100−002 (EIA/JESD22−A114)
ESD MM tested per AEC−Q100−003 (EIA/JESD22−A115)
Field Induced Charge Device Model ESD characterization is not performed on plastic molded packages with body sizes <50mm
2
due to the
inability of a small package body to acquire and retain enough charge to meet the minimum CDM discharge current waveform characteristic
defined in JEDEC JS−002−2014.
