APPLICATIONS INFORMATION General Information low equivalent series resistance (ESR) capacitor across the input supply near the regulator. The NCP59800 is designed to be stable with standard ceramic output capacitors of capacitance values 4.7 mF up to 100 mF. This device is evaluated using a 4.7 mF/10 V, 10% tolerance, X5R type Ceramic Capacitors of 0805 size. X5R− and X7R−type capacitors are highly recommended because they have minimal variation in value and ESR over temperature. Maximum ESR should be < 1.0 W. The NCP59800 regulator is equipped with Noise Reduction pin (NR) for noise sensitive applications. A noise reduction capacitor (CNR) at the NR pin bypasses noise generated by the bandgap reference. This family of regulators offers sub−bandgap output voltages, current limit, and thermal protection, and is fully specified from –40°C to +125°C. assuming resistors with zero error. For the actual design, pay attention to any resistor error factors. Figure 3 gives the connections for the adjustable output version (NCP59800BMNADJTBG). Startup Response The CNR serves not only for noise reduction. Slow ramping of Voltage Reference (adjustable Soft−Start) is reducing the Inrush Current as well.
