1 / 10 page © Semiconductor Components Industries, LLC, 2015 December, 2015 − Rev. 0 1 Publication Order Number: NCV4949C/D NCV4949C 100 mA, 5.0 V, Low Dropout Voltage Regulator with Reset and Sense The NCV4949C is a monolithic integrated 5.0 V voltage regulator with a very low dropout and additional functions such as reset and an uncommitted voltage sense comparator. It is designed for supplying microcontroller/microprocessor controlled systems particularly in automotive applications. The NCV4949C has improved reset behavior for lower input and output voltage levels. Features • Operating DC Supply Voltage Range 5.5 V to 40 V • High Precision Output Voltage 5.0 V ±1% • Output Current Capability Up to 100 mA • Very Low Dropout Voltage Less Than 0.4 V • Reset Circuit Sensing The Output Voltage • Programmable Reset Pulse Delay • Voltage Sense Comparator • Fault Protection, +60 V Peak Transient Voltage, −40 V Reverse Voltage, Short Circuit, Thermal Overload • NCV Prefix for Automotive and Other Applications Requiring Site and Change Control • These are Pb−Free Devices Regulator Vref 2.0 mA Reset Sense GND Sense Output (So) Reset Sense Input (Si) Supply Voltage (VCC) NC Output Voltage (Vout) CT 3 84 6 7 5 2 1 Figure 1.
