NCP5662, NCV5662 Low Output Voltage, Ultra-Fast 2.0 A Low Dropout Linear Regulator with Enable The NCP5662/NCV5662 is a high performance, low dropout linear regulator designed for high power applications that require up to 2.0 A www.onsemi.com current. It is offered in both fixed and adjustable output versions. With output voltages as low as 0.9 V and ultrafast response times for load MARKING DIAGRAMS AND transients, the NCP5662/NCV5662 also provides additional features PIN ASSIGNMENTS such as Enable and Error Flag (for the fixed output version), increasing the utility of these devices. A thermally robust, 5 pin 2 D PAK or DFN8 package, combined with an architecture that offers Tab = GND NC Pin 1 = EN low ground current (independent of load), provides for a superior 1 x5662DSy 2 = V in highcurrent LDO solution. 5 AWLYWWG 3 = GND 2 D PAK 4 = V out Features DS SUFFIX 1 5 = ADJ/EF CASE 936A02 UltraFast Transient Response (Settling Time: 13 s) Low Noise Without Bypass Capacitor (26 V rms) Low Ground Current Independent of Load (3.0 mA Maximum) Fixed/Adjustable Output Voltage Versions NCP5 662y 1 Enable Function ALYW DFN8 Error Flag (Fixed Output Version) MN SUFFIX Current Limit Protection CASE 488AF Thermal Shutdown Protection (160C) Fixed Version Adjustable Version 0.9 V Reference Voltage for UltraLow Output Operation Pin 1 = EF Pin 1 = ADJ Power Supply Rejection Ratio > 65 dB 2 = GND 2 = GND 3 = N/C 3 = N/C NCV Prefix for Automotive and Other Applications Requiring 4 = EN 4 = EN Unique Site and Control Change Requirements AECQ100 5, 6 = V 5, 6 = V in in Qualified and PPAP Capable 7, 8 = V 7 = V out out 8 = N/C These are PbFree Devices x = P or V Applications y = A for Adjustable Version Servers B for Fixed 1.5 V Version C for Fixed 3.3 V Version ASIC Power Supplies D for Fixed 1.2 V Version Post Regulation for Power Supplies E for Fixed 1.8 V Version F for Fixed 2.5 V Version Constant Current Source G for Fixed 2.8 V Version Networking Equipment H for Fixed 3.0 V Version Gaming and STB Modules A = Assembly Location L = Wafer Lot Y = Year WW = Work Week G or = PbFree Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 13 of this data sheet.
