ncp58300 http://onsemi.com 9 applications information output capacitor and stability the ncp58300 series requires an output capacitor for stable operation. the ncp58300 series is designed to operate with tantalum output capacitors. the recommended output capacitance value is 10 f or greater. higher value helps to improve transient response and noise reduction. the value of output capacitor is dependent upon the output current; lower currents allow smaller capacitors. input capacitor an input capacitor of 0.1 f or greater is recommended when the device is more than 4 inches away from the bulk supply capacitance, or when the supply is a battery. small, surface ? mount chip capacitors can be used for the bypassing. the capacitor should be place within 1 inch of the device for optimal performance. larger values will help to improve ripple rejection by bypassing the input of the regulator, further improving the integrity of the output voltage. minimum load current the ncp58300 regulator is specified between finite loads. a 7 ma minimum load current is necessary for proper operation. error flag some ncp58300 series members feature an error flag circuit that monitors the output voltage and signals an error condition when the voltage is 5% below the nominal output voltage. the error flag is an open ? collector output that can sink up to 10 ma during a v out fault condition. the flg output is overload protected when a short circuit of the pullup load resistor occurs in the application. this is guaranteed in the full range of flg output voltage max ratings (see max ratings table). enable input some ncp58300 series members also feature an enable input for on/off control of the device. it?s shutdown state draws ?zero? current from input voltage supply (only microamperes of leakage). the enable input is ttl/cmos compatible for simple logic interface, but can be connected up to v in . overcurrent and reverse output current protection the ncp58300 regulator is fully protected from damage due to output current overload conditions. when ncp58300 output is overloaded, output current limiting is provided. this limiting is linear; output current during overload conditions is constant. the device is also capable to withstand power ? on or enable start ? up with output shorted to ground for the full recommended operating conditions range. these features are advantageous for powering fpgas and other ics having current consumption higher than nominal during their startup. thermal shutdown disables the ncp58300 device when the die temperature exceeds the maximum safe operating temperature. when ncp58300 is disabled and (v out ? v in ) voltage difference is less than 6.5 v in the application, the output structure of these regulators is able to withstand output voltage (backup battery as example) to be applied without reverse current flow. of course the additional current flowing through the internal feedback resistor divider at the ncp58300 fix voltage versions needs to be included in the backup battery discharging calculations. adjustable voltage design the ncp/ncv58302 adjustable voltage device output voltage is set by the ratio of two external resistors as shown in figure 18.the device maintains the voltage at the adj pin at 1.24 v referenced to ground. the current in r2 is then equal to1.24 v / r2, and the current in r1 is the current in r2 plus the adj pin bias current. the adj pin bias current flows from vout through r1 into the adj pin. figure 18. adjustable voltage operation v out 1.24 v 1 r1 r2 i adj r1 + + vin en vout adj gnd ncp58302 r1 r2 v out v in c in c out 10 f, tantalum for the r2 resistor value up to 15 k the i adj current impact can be neglected and the r1 resistor value can be calculated y: r1 r2 v out 1.24 1 (eq. 1) where v out is the desired nominal output voltage. thermal considerations the power handling capability of the device is limited by the maximum rated junction temperature (125 c). the p d total power dissipated by the device has two components, input to output voltage differential multiplied by output current and input voltage multiplied by gnd pin current. p d v in v out i out v in i gnd (eq. 2) the gnd pin current value can be found in electrical characteristics table and in typical characteristics graphs. the junction temperature t j is t j t a p d r ja (eq. 3) where t a is ambient temperature and r ja is the junction to ambient thermal resistance of the ncp/ncv58300 device mounted on the specific pcb.
