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.
