NCP59800 www. onsemi.com 5 applications information general information the NCP59800 regulator is equipped with noise reduction pin (nr) for noise sensitive applications. a noise reduction capacitor (c nr ) 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 typical application schematics. figure 3. typical application schematics in en out fb nr gnd optional 10 nf v in c in 1 f v out 4.7 f c out r 2 r 1 NCP59800 output voltage setting the output voltage can be adjusted from 0.8 v to 5.0 v using resistors divider between the output and the fb input. the values of r1 and r2 can be calculated for any voltage using the following formula: v out 0.8 v 1 r 1 r 2 recommended resistor values for frequently used voltages can be found in the table 6. capacitors selection although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1 f to 1.0 f 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 f up to 100 f. this device is evaluated using a 4.7 f/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. startup response the c nr serves not only for noise reduction. during start?up the c nr capacitor works like the soft start timing capacitor. the controlled monotonic ramping of voltage reference (adjustable soft?start) is limiting the inrush current. table 6. recommended 1% feedback resistor values for frequently used nominal output voltages v out r 1 r 2 0.8 v 0 (short) 10.0 k 1.0 v 2.49 k 10.0 k 1.2 v 4.99 k 10.0 k 1.5 v 8.87 k 10.0 k 1.8 v 12.5 k 10.0 k 2.5 v 21.0 k 10.0 k 3.3 v 30.9 k 10.0 k 5.0 v 52.3 k 10.0 k power dissipation the maximum power dissipation supported by the device is dependent upon board design and layout. mounting pad configuration on the pcb, the board material, and the ambient temperature affect the rate of junction temperature rise for the part. for reliable operation junction temperature should be limited to +125 c. table 7. ordering information device output voltage marking package shipping ?
