ncp629 http://onsemi.com 9 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 2% below its nominal. 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 . disable and ground current ground current (i gnd ) is the current that flows through the ground pin when the regulator operates with a load on its output. 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 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 at which the junction temperature reaches its maximum operating value. applications information the ncp629 series regulator is self-protected with internal thermal shutdown and internal current limit. t ypical application circuit is shown in figure 1. input decoupling (c in ) a ceramic or tantalum 1.0 f capacitor is recommended and should be connected close to the ncp629 package. higher capacitance and lower esr will improve the overall line transient response. output decoupling (c out ) the ncp629 is a stable component and does not require a minimum equivalent series resistance (esr) for the output capacitor. the minimum output decoupling value is 1.0 f and can be augmented to fulfill stringent load transient requirements. the regulator works with ceramic chip capacitors as well as tantalum devices. typical characteristics were measured with murata ceramic capacitors grm31mr71e105ka01 (1.0 f, 25 v x7r, 1206). larger values improve noise rejection and load regulation transient response. figure 23 shows the stability region for a range of operating conditions and esr values. no-load regulation considerations the ncp629 contains 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, thus guaranteeing that the clamp circuit is active whenever leakage current is present.
ncp629 http://onsemi.com 10 noise decoupling the ncp629 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 ncp629 operates without a noise reduction capacitor, has a typical 15 s startup delay 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 . thermal as power in the ncp629 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 ncp629 has good thermal conductivity through the pcb, the junction temperature will be relatively low with high power applications. the maximum dissipation the ncp629 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 125 c, then the ncp629 soldered on 645 mm2, 1 oz copper area, fr4 can dissipate up to 360 mw when the ambient temperature (t a ) is 25 c. see figure 26 for r thja versus pcb area. the power dissipated by the ncp629 can be calculated from the following equations: (eq. 2) p d v in i gnd @i out i out v in v out or v in(max) p d(max) (v out i out ) i out i gnd (eq. 3) 200 220 240 260 280 300 320 340 0 100 200 300 400 500 600 700 figure 26. r thja vs. pcb copper area pcb copper area (mm 2 ) r thja , thermal resistance junction-to-ambient ( c/w) (1 oz) (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 ncp629, and make traces as short as possible. device ordering information device version marking code package shipping ? ncp629fc15t2g 1.5 v aaa 5 pin flip-chip 3000/tape & reel ncp629fc18t2g 1.8 v aac NCP629FC28T2G 2.8 v aad ncp629fc30t2g 3.0 v aae ncp629fc33t2g 3.3 v aaf ncp629fc35t2g 3.5 v aag ncp629fc50t2g 5.0 v aah ?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.
