NCV8774 http://onsemi.com 10 definitions general all measurements are performed using short pulse low duty cycle techniques to maintain junction temperature as close as possible to ambient temperature. output voltage the output voltage parameter is defined for specific temperature, input voltage and output current values or specified over line, load and temperature ranges. line regulation the change in output voltage for a change in input voltage measured for specific output current over operating ambient temperature range. load regulation the change in output voltage for a change in output current measured for specific input voltage over operating ambient temperature range. dropout voltage the input to output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. it is measured when the output drops 100 mv below its nominal value. the junction temperature, load current, and minimum input supply requirements affect the dropout level. quiescent and disable currents quiescent current (i q ) is the difference between the input current (measured through the ldo input pin) and the output load current. current limit and short circuit current limit current limit is value of output current by which output voltage drops below 96% of its nominal value. short circuit current limit is output current value measured with output of the regulator shorted to ground. psrr power supply rejection ratio is defined as ratio of output voltage and input voltage ripple. it is measured in decibels (db). line transient response typical output voltage overshoot and undershoot response when the input voltage is excited with a given slope. load transient response typical output voltage overshoot and undershoot response when the output current is excited with a given slope between low ? load and high ? load conditions. thermal protection internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. when activated at typically 175 c, the regulator turns off. this feature is provided to prevent failures from accidental overheating. maximum package power dissipation the power dissipation level is maximum allowed power dissipation for particular package or power dissipation at which the junction temperature reaches its maximum operating value, whichever is lower.
NCV8774 http://onsemi.com 11 applications information the NCV8774 regulator is self ? protected with internal thermal shutdown and internal current limit. typical characteristics are shown in figures 4 to 26. input decoupling (c in ) a ceramic or tantalum 0.1 f capacitor is recommended and should be connected close to the NCV8774 package. higher capacitance and lower esr will improve the overall line and load transient response. if extremely fast input voltage transients are expected then appropriate input filter must be used in order to decrease rising and/or falling edges below 50 v/ s for proper operation. the filter can be composed of several capacitors in parallel. output decoupling (c out ) the NCV8774 is a stable component and does not require a minimum equivalent series resistance (esr) for the output capacitor. stability region of esr vs output current is shown in figure 17. the minimum output decoupling value is 1 f and can be augmented to fulfill stringent load transient requirements. the regulator works with ceramic chip capacitors as well as tantalum devices. larger values improve noise rejection and load regulation transient response. thermal considerations as power in the NCV8774 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. when the NCV8774 has good thermal conductivity through the pcb, the junction temperature will be relatively low with high power applications. the maximum dissipation the NCV8774 can handle is given by: p d ( max ) t j(max) t a r ja (eq. 1) since t j is not recommended to exceed 150 c, then the NCV8774 soldered on 645 mm 2 , 1 oz copper area, fr4 can dissipate up to 2.35 w when the ambient temperature (t a ) is 25 c. see figure 27 for r ja versus pcb area. the power dissipated by the NCV8774 can be calculated from the following equations: p d v in i q @i out
i out v in v out (eq. 2) or v in(max) p d(max)
v out i out i out
i q (eq. 3) note: items containing i q can be neglected if i out >> i q . 40 50 60 70 80 90 100 0 100 200 300 400 500 600 700 figure 27. thermal resistance vs. pcb copper area copper heat spreader (mm 2 ) r ja , thermal resistance ( c/w) dpak 1 oz dpak 2 oz hints v in and gnd printed circuit board traces should be as wide as possible. when the impedance of these traces is high, there is a chance to pick up noise or cause the regulator to malfunction. place external components, especially the output capacitor, as close as possible to the NCV8774 and make traces as short as possible. ordering information device output voltage marking package shipping ?
