NCV4274C
400 mA Low Dropout
Voltage Regulator
Description
The NCV4274C is a precision micro−power voltage regulator with
an output current capability of 400 mA available in the DPAK and
D2PAK 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.
Features
• 3.3 V, 5.0 V, ±2.0% Output Options
• Low 125 mA Quiescent Current at 1 mA load current
• 400 mA Output Current Capability
• Fault Protection
• +60 V Peak Transient Voltage with Respect to GND
S −42 V Reverse Voltage
S Short Circuit
S Thermal Overload
• Very Low Dropout Voltage
• AEC−Q100 Grade 1 Qualified and PPAP Capable
• These are Pb−Free Devices
