NCV4274, NCV4274A Regulator Family, 400 mA, 2% and 4% Voltage Description The NCV4274 and NCV4274A is a precision micropower voltage regulator with an output current capability of 400 mA available in the www.onsemi.com DPAK, D2PAK and SOT223 packages. The output voltage is accurate within 2.0% or 4.0% depending on MARKING DIAGRAMS 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 A with a 4 1 mA load. This part is ideal for automotive and all battery operated microprocessor equipment. 74XxxG 1 Input ALYWW The regulator is protected against reverse battery, short circuit, and 2, 4 Ground x DPAK thermal overload conditions. The device can withstand load dump 3 Output DT SUFFIX transients making it suitable for use in automotive environments. 2 CASE 369C 1 3 Features 2.5, 3.3 V, 5.0 V, 8.5 V, 2.0% Output Options 4 2.5, 3.3 V, 5.0 V, 4.0% Output Options Low 150 A Quiescent Current at 1 mA load current 1 Input NC 400 mA Output Current Capability 2, 4 Ground V4274Xxx 3 Output Fault Protection AWLYWWG D2PAK +60 V Peak Transient Voltage with Respect to GND DS SUFFIX 42 V Reverse Voltage CASE 418AF Short Circuit 123 Thermal Overload 4 Very Low Dropout Voltage NCV Prefix for Automotive and Other Applications Requiring AYW 1 Input Unique Site and Control Change Requirements AECQ100 74Xxx 2, 4 Ground Qualified and PPAP Capable SOT223 3 Output ST SUFFIX These are PbFree Devices CASE 318E 1 23 X = A or blank xx = Voltage Ratings A = Assembly Location L, WL = Wafer Lot Y = Year WW, W = Work Week G, = PbFree Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 15 of this data sheet.
