DATA SHEET www.onsemi.com Linear Regulator - Dual-Rail, Very Low-Dropout, QFN20 DFN10 WLCSP10 CASE 485DB CASE 485C CASE 567ZC Programmable Soft-Start MARKING DIAGRAMS 3.0 A 1 1 NCP NCP59744 NCP59744 59744 AWLYYWW AYW The NCP59744 is dualrail very low dropout voltage regulator that is capable of providing an output current in excess of 3.0 A with a QFN20 DFN10 dropout voltage of 75 mV typ. at full load current. The devices are stable with ceramic and other low ESR output capacitors. This series 59744 contains adjustable output voltage version with output voltage down ALYWW to 0.8 V. Internal protection features consist of builtin thermal shutdown and output current limiting protection. Userprogrammable WLCSP10 SoftStart and Power Good pins are available. The NCP59744 is A = Assembly Location offered in DFN10 3x3, QFN20 5x5 and WLCSP10 packages.
