NCP59749

NCP59749 Linear Regulator Dual-Rail, Very Low‐Dropout, Programmable Soft‐Start 3.0 A The NCP59749 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 NCP59749 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 These are Pb−Free Devices Applications Consumer and Industrial Equipment Point of Load Regulation FPGA, DSP and Logic Power Supplies Switching Power Supply Post Regulation NCP59749 http://onsemi.com QFN20 CASE 485DB PIN CONNECTIONS IN NC NC NC OUT IN IN IN PG BIAS 54321 6 20 7 19 8 GND 18 9 17 10 16 11 12 13 14 15 OUT OUT OUT NC FB EN GND NC NC SS QFN20, 5x5, 0.65P MARKING DIAGRAM 1 XXXXXXXX XXXXXXXX AWLYYWWG G QFN20 XXXXX = Specific Device Code A = Assembl...
