NCV4274, NCV4274A
400 mA 2% and 4%Voltage
Regulator Family
Description
The NCV4274 and NCV4274A 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% or ±4.0% depending on
the version with a maximum dropout voltage of 0.5 V with an input up
to 40 V. Low quiescent current is a feature drawing only 150 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
• 2.5, 3.3 V, 5.0 V, ±2.0% and ±4.0% Output Options
• Low 150 mA Quiescent Current at 1 mA load current
• 400 mA Output Current Capability
• Fault Protection
• +60 V Peak Transient Voltage with Respect to GND
• −40 V Reverse Voltage
• Short Circuit
• Thermal Overload
• Very Low Dropout Voltage
• Electrical Parameters Guaranteed Over Entire Temperature Range
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• These are Pb−Free Devices
