NCP114 http://onsemi.com 12 applications information general the NCP114 is a high performance 300 ma low dropout linear regulator. this device delivers very high psrr (over 75 db at 1 khz) and excellent dynamic performance as load/line transients. in connection with very low quiescent current this device is very suitable for various battery powered applications such as tablets, cellular phones, wireless and many others. the device is fully protected in case of output overload, output short circuit condition and overheating, assuring a very robust design. input capacitor selection (c in ) it is recommended to connect at least a 1 f ceramic x5r or x7r capacitor as close as possible to the in pin of the device. 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 min. /max. 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. larger input capacitor may be necessary if fast and large load transients are encountered in the application. output decoupling (c out ) the NCP114 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 NCP114 is designed to remain stable with minimum effective capacitance of 0.22 f to account for changes with temperature, dc bias and package size. especially for small package size capacitors such as 0402 the effective capacitance drops rapidly with the applied dc bias. 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 NCP114 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 100 resistor. in the disable state the device consumes as low as typ. 10 na from the v in . if the en pin voltage >0.9 v the device is guaranteed to be enabled. the NCP114 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 300 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 600 ma. the NCP114 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 630 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 NCP114 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 ambient temperature affect the rate of junction temperature rise for the part. the maximum power dissipation the NCP114 can handle is given by: p d(max) 125 c t a ja (eq. 1) the power dissipated by the NCP114 for given application conditions can be calculated from the following equations: p d v in i gnd @i out i out v in v out (eq. 2)
