NCP4632DDT08T5G ON Semiconductor

NCP4632 3A, Low Voltage, Low Dropout Linear Voltage Regulator with Reverse Current Protection www.onsemi.com The NCP4632 is a CMOS Linear voltage regulator with high output current capability (up to 3 A). This device can provide output voltages MARKING as low as 0.8 V while maintaining a low dropout voltage of 510 mV DIAGRAM typ. at full load. The NCP4632 is designed to draw only 350 A of supply current and less than 1 A in standby mode to minimize current consumption for battery operated applications. The device has a high E1Jxx1 accuracy output voltage of 1% along with softstart and reverse yy zz current protection circuits to protect the device and the application. DPAK5 The NCP4632 is available in a PbFree DPAK5 package in both CASE 369AE fixed and adjustable output voltage options. The output voltage for the fixed options can be modified in 0.1 V steps from 0.8 V to 4.2 V 12 3 4 5 Please contact your sales office for any additional fixed voltage outputs to those already listed. xx = Specific Device Code YY = B Without Active Discharge Features = D With Active Discharge Operating Input Voltage Range: 1.6 V to 5.25 V zz = Lot Number Output Voltage Range: 0.8 to 4.5 V (0.1 V steps for fixed options) Supply current: Typical Operation Mode 350.0 A Standby Mode 1.0 A ORDERING INFORMATION Dropout Voltage: See detailed ordering and shipping information in the package dimensions section on page 13 of this data sheet. 150 mV Typ. at I = 1 A, V = 2.5 V OUT OUT 510 mV Typ. at I = 3 A, V = 2.5 V OUT OUT 1% Output Voltage Accuracy Line Regulation 0.15%/V Typ.
