NCV8664C Linear Regulator, Low Dropout, Very Low I q The NCV8664C is a precision 3.3 V and 5.0 V fixed output, low dropout integrated voltage regulator with an output current capability of 150 mA. Careful management of light load current www.onsemi.com consumption, combined with a low leakage process, achieve a typical quiescent current of 22 A. NCV8664C is pin and functionally compatible with NCV42642C MARKING and could replace this part when lower quiescent current is required. DIAGRAMS The output voltage is accurate within 2.0%, and maximum dropout voltage is 600 mV at full rated load current. It is internally protected against input supply reversal, output TAB AYW SOT223 664Cx ST SUFFIX overcurrent faults, and excess die temperature. No external 1 2 CASE 318E components are required to enable these features. 3 1 Features 3.3 V, 5.0 V Fixed Output 4 2.0 % Output Accuracy, Over Full Temperature Range DPAK 664CxxG DT SUFFIX 22 A Typical Quiescent Current ALYWW CASE 369C 2 1 600 mV Maximum Dropout Voltage at 150 mA Load Current 3 1 Wide Input Voltage Operating Range of 4.5 V to 45 V Internal Fault Protection 42 V Reverse Voltage xx = Voltage Rating DPAK Short Circuit/Overcurrent (50 = 5.0 V Version) (33 = 3.3 V Version) Thermal Overload x = Voltage Rating SOT223 NCV Prefix for Automotive and Other Applications Requiring (5 = 5.0 V Version) Unique Site and Control Change Requirements AECQ100 (3 = 3.3 V Version) Qualified and PPAP Capable A = Assembly Location L = Wafer Lot EMC Compliant Y = Year These are PbFree Devices WW = Work Week or G = PbFree Package (Note: Microdot may be in either location) PIN CONNECTIONS (SOT223/DPAK) PIN FUNCTION 1V IN 2,4,TAB GND 3V OUT ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 11 of this data sheet.
