NCP59748

Linear Regulator Dual-Rail, Very Low‐Dropout, Programmable Soft‐Start 1.5 A NCP59748 The NCP59748 is dual−rail very low dropout voltage regulator, capable of providing an output current in excess of 1.5 A with a dropout voltage of 60 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 on both QFN and DFN versions. The NCP59748 is offered in DFN10 3×3 and QFN20 5×5 packages. Features Output Current in Excess of 1.5 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: 60 mV at 1.5 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 NCP59748 DATA SHEET www.onsemi.com QFN20 CASE 485DB DFN10 CASE 485C 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 QFN20−5y5−0.65P IN 1 IN 2 PG 3 BIAS 4 E...
