ncv8163 www. onsemi.com 12 applications information general the ncv8163 is an ultra ? low noise 250 ma low dropout regulator designed to meet the requirements of rf applications and high performance analog circuits. the ncv8163 device provides very high psrr and excellent dynamic response. in connection with low quiescent current this device is well suitable for battery powered application such as cell phones, tablets and other. the ncv8163 is fully protected in case of current overload, output short circuit and overheating. input capacitor selection (c in ) input capacitor connected as close as possible is necessary for ensure device stability. the x7r or x5r capacitor should be used for reliable performance over temperature range. the value of the input capacitor should be 1 f or greater to ensure the best dynamic performance. this capacitor will provide a low impedance path for unwanted ac signals or noise modulated onto constant input voltage. there is no requirement for the esr of the input capacitor but it is recommended to use ceramic capacitors for their low esr and esl. a good input capacitor will limit the influence of input trace inductance and source resistance during sudden load current changes. output decoupling (c out ) the ncv8163 requires an output capacitor connected as close as possible to the output pin of the regulator. the recommended capacitor value is 1 f and x7r or x5r dielectric due to its low capacitance variations over the specified temperature range. the ncv8163 is designed to remain stable with minimum ef fective capacitance of 0.7 f to account for changes with temperature, dc bias and package size. especially for small package size capacitors such as 0201 the ef fective capacitance drops rapidly with the applied dc bias. please refer figure 47. figure 47. capacity vs dc bias voltage there is no requirement for the minimum value of equivalent series resistance (esr) for the c out but the maximum value of esr should be less than 2 . larger output capacitors and lower esr could improve the load transient response or high frequency psrr. it is not recommended to use tantalum capacitors on the output due to their large esr. the equivalent series resistance of tantalum capacitors is also strongly dependent on the temperature, increasing at low temperature. enable operation the ncv8163 uses the en pin to enable/disable its device and to deactivate/activate the active discharge function. if the en pin voltage is <0.4 v the device is guaranteed to be disabled. the pass transistor is turned ? off so that there is virtually no current flow between the in and out. the active discharge transistor is active so that the output voltage v out is pulled to gnd through a 280 resistor. in the disable state the device consumes as low as typ. 10 na from the v in . if the en pin voltage >1.2 v the device is guaranteed to be enabled. the ncv8163 regulates the output voltage and the active discharge transistor is turned ? off. the en pin has internal pull ? down current source with typ. value of 200 na which assures that the device is turned ? off when the en pin is not connected. in the case where the en function isn?t required the en should be tied directly to in. output current limit output current is internally limited within the ic to a typical 700 ma. the ncv8163 will source this amount of current measured with a voltage drops on the 90% of the nominal v out . if the output voltage is directly shorted to ground (v out = 0 v), the short circuit protection will limit the output current to 690 ma (typ). the current limit and short circuit protection will work properly over whole temperature range and also input voltage range. there is no limitation for the short circuit duration. thermal shutdown when the die temperature exceeds the thermal shutdown threshold (t sd ? 160 c typical), thermal shutdown event is detected and the device is disabled. the ic will remain in this state until the die temperature decreases below the thermal shutdown reset threshold (t sdu ? 140 c typical). once the ic temperature falls below the 140 c the ldo is enabled again. the thermal shutdown feature provides the protection from a catastrophic device failure due to accidental overheating. this protection is not intended to be used as a substitute for proper heat sinking. power dissipation as power dissipated in the ncv8163 increases, it might become necessary to provide some thermal relief. 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

ncv8163 www. onsemi.com 14 reverse current the pmos pass transistor has an inherent body diode which will be forward biased in the case that v out > v in . due to this fact in cases, where the extended reverse current condition can be anticipated the device may require additional external protection. power supply rejection ratio the ncv8163 features very high power supply rejection ratio. if desired the psrr at higher frequencies in the range 100 khz ? 10 mhz can be tuned by the selection of c out capacitor and proper pcb layout. turn ? on time the turn ? on time is defined as the time period from en assertion to the point in which v out will reach 98% of its nominal value. this time is dependent on various application conditions such as v out(nom) , c out , t a . pcb layout recommendations to obtain good transient performance and good regulation characteristics place c in and c out capacitors close to the device pins and make the pcb traces wide. in order to minimize the solution size, use 0402 or 0201 capacitors with appropriate capacity. larger copper area connected to the pins will also improve the device thermal resistance. the actual power dissipation can be calculated from the equation above (equation 2). expose pad can be tied to the gnd pin for improvement power dissipation and lower device temperature. ordering information device voltage option marking description package shipping ? ncv8163amx120tbg 1.2 v me 250 ma, active discharge xdfn4 case 711aj (pb-free) 3000 / tape & reel ncv8163amx150tbg 1.5 v mv ncv8163amx180tbg 1.8 v ma ncv8163amx250tbg 2.5 v mu NCV8163AMX270TBG 2.7 v mx ncv8163amx280tbg 2.8 v mm ncv8163amx300tbg 3.0 v mj ncv8163amx330tbg 3.3 v mk ncv8163amx400tbg 4.0 v my ncv8163asn120t1g 1.2 v mke 250 ma, active discharge tsop ? 5 case 483 (pb-free) 3000 / tape & reel ncv8163asn180t1g 1.8 v kaa ncv8163asn270t1g 2.7 v kak ncv8163asn280t1g 2.8 v kae ncv8163asn300t1g 3.0 v kaf ncv8163asn330t1g 3.3 v kag ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specifications brochure, brd8011/d.
