ncp690, ncp691, ncp692, ncv8690 http://onsemi.com 12 definitions load regulation the change in output voltage for a change in output load current at a constant temperature. dropout voltage the input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. 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. output noise voltage this is the integrated value of the output noise over a specified frequency range. input voltage and output load current are kept constant during the measurement. results are expressed in v rms or nv hz. ground current ground current is the current that flows through the ground pin when the regulator operates without a load on its output (i gnd ). this consists of internal ic operation, bias, etc. it is actually the difference between the input current (measured through the ldo input pin) and the output load current. if the regulator has an input pin that reduces its internal bias and shuts off the output (enable/disable function), this term is called the disable current (i dis .) line regulation the change in output voltage for a change in input voltage. the measurement is made under conditions of low dissipation or by using pulse techniques such that the average junction temperature is not significantly affected. 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 no ? load and full ? 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 at which the junction temperature reaches its maximum operating value. applications information the ncp690 regulator is self ? protected with internal thermal shutdown and internal current limit. typical application circuit is shown in figure 1. input decoupling (c in ) a ceramic 10 f capacitor is recommended and should be connected close to the ncp690 package. higher capacitance and lower esr will improve the overall line transient response. output decoupling (c out ) the ncp690 does not require a minimum equivalent series resistance (esr) for the output capacitor. the minimum output decoupling capacitor required for stability is 1 f. in order to improve the load transient response and start up performance 10 f capacitor is recommended. the regulator is stable with ceramic chip as well as tantalum capacitors. larger values improve noise rejection and load transient response. no ? load regulation considerations the required minimum 100 a load current is assured by the internal resistor divider network. the ncp690 contain an overshoot clamp circuit to improve transient response during a load current step release. when output voltage exceeds the nominal by approximately 20 mv, this circuit becomes active and clamps the output from further voltage increase. tying the enable pin to v in will ensure that the part is active whenever the supply voltage is present, noise decoupling the ncp690 is a low noise regulator and needs no external noise reduction capacitor. unlike other low noise regulators which require an external capacitor and have slow startup times, the ncp690 operates without a noise reduction capacitor, has a typical 50 s turn ? on time and achieves a 50 v rms overall noise level between 10 hz and 100 khz. enable operation the enable pin will turn the regulator on or off. the threshold limits are covered in the electrical characteristics table in this data sheet. the turn ? on/turn ? off transient voltage being supplied to the enable pin should exceed a slew rate of 10 mv/ s to ensure correct operation. if the enable function is not to be used then the pin should be connected to v in . adjustable operation the output voltage can be adjusted from 1 to 4 times the typical 1.250 v regulation voltage by the use of resistor
