1 / 10 page © Semiconductor Components Industries, LLC, 2017 February, 2017 − Rev. 1 1 Publication Order Number: NCV59749/D NCV59749 3.0 A, Dual-Rail Very Low‐Dropout Linear Regulator with Programmable Soft‐Start The NCV59749 is dual−rail very low dropout voltage regulator that is capable of providing an output current in excess of 3.0 A with a dropout voltage of 120 mV typ. at full load current. The devices are stable with ceramic and any other type of output capacitor ≥ 2.2 mF. This series contains adjustable output voltage version with output voltage down to 0.8 V. Internal protection features consist of built−in thermal shutdown and output current limiting protection. User−programmable Soft−Start and Power Good pins are available. The NCV59749 is available in QFN20 5x5 package. Features • Output Current in Excess of 3.0 A • VIN Range: 0.8 V to 5.5 V • VBIAS Range: 2.7 V to 5.5 V • Output Voltage Range: 0.8 V to 3.6 V • Dropout Voltage: 120 mV at 3 A • Programmable Soft Start • Open Drain Power Good Output • Fast Transient Response • Stable with Any Type of Output Capacitor ≥ 2.2 mF • Current Limit and Thermal Shutdown Protection • NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • These are Pb−Free Devices Applications • Automotive, Consumer and Industrial Equipment Point of Load Regulation • FPGA, DSP and Logic Power Supplies • Switching Power Supply Post Regulation Figure 1.
