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