6 apr 20-07 rev b spx1117 800ma low dropout voltage regulator ? 2007 sipex corporation output capacitor to ensure the stability of the spx1117, an output capacitor of at least 2.2 f (tantalum or ceramic) or 10 f (aluminum) is required. the value may change based on the application requirements of the output load or temperature range. the value of esr can vary based on the type of capacitor used in the applications to guarantee stability. the recommended value for esr is 0.5 ? or less. a larger value of output capacitance (up to 100 f) can improve the load transient response. soldering methods the spx1117 sot-223 package is designed to be compatible with infrared reflow or vapor-phase reflow soldering techniques. during soldering, the non-active or mildly active fluxes may be used. the spx1117 die is attached to the heatsink lead which exits opposite the input, output, and ground pins. hand soldering and wave soldering should be avoided since these methods can cause damage to the device with excessive thermal gradients on the package. the sot-223 recommended soldering method are as follows: vapor phase reflow and infrared reflow with the component preheated to within 65 c of the soldering temperature range. figure 16. load step response (0 to 800ma), vin=3.3v, vout=1.8v, cin=10 f, cout=2.2 f, ceramic; 1 = vout, 4= iload figure 17. load step response (0 to 800ma), vin=3.3v, vout=1.8v, cin=10 f, cout=2.2 f, oscon; 1 = vout, 4= iload application information
7 apr 20-07 rev b spx1117 800ma low dropout voltage regulator ? 2007 sipex corporation thermal characteristics the thermal resistance of spx1117 (sot-223 package) is 15 c/w from junction to tab and 31 c/w from tab to ambient for a total of 46 c/w from junction to ambient (table 1). the spx1117 features the internal thermal limiting to protect the device during overload conditions. special care needs to be taken during continuous load conditions such that the maximum junction tem - perature does not exceed 125 c. thermal pro - tection is activated at >155 c and deactiviated at <140 c. taking the fr-4 printed circuit board and 1/16 thick with 1 ounce copper foil as an experiment (fig.13), the pcb material is effective at trans - mitting heat with the tab attached to the pad area and a ground plane layer on the backside of the substrate. refer to table 1 for the results of the experiment. the thermal interaction from other components in the application can effect the thermal resis - tance of the spx1117. the actual thermal resistance can be determined with experimenta - tion. spx1117 power dissipation is calculated as follows: p d = (v in - v out )(i out ) maximum junction temperature range: t j = t a (max) + p d * thermal resistance (junction-to-ambient) maximum junction temperature must not ex - ceed the 125 c. ripple rejection ripple rejection can be improved by adding a capacitor between the adj pin and ground as shown in figure 23. when adj pin bypassing is used, the value of the output capacitor re - quired increases to its maximum. if the adj pin is not bypassed, the value of the output capacitor can be lowered to 10 f for an electrolytic alu - minum capacitor or 2.2 f for a ceramic or solid tantalum capacitor (fig 22). however the value of the adj-bypass capacitor should be chosen with respect to the following equation: c = 1 / ( 6.28 * f r * r 1 ) where c = value of the capacitor in farads (select an equal or larger standard value), f r = ripple frequency in hz, r 1 = value of resistor r1 in ohms. if an adj-bypass capacitor is used, the ampli - tude of the output ripple will be independent of the output voltage. if an adj-bypass capacitor is not used, the output ripple will be proportional to the ratio of the output voltage to the reference voltage: m = v out / v ref where m = multiplier for the ripple seen when the adj pin is optimally bypassed. v ref =1.25v ripple rejection for the adjustable version is shown in figure 20. figure 19. substrate layout for sot-223 50 x 50mm 35 x 17mm 16 x 10mm -90 -80 -70 -60 -50 -40 -30 -20 -10 0 10 100 1000 10000 100000 1000000 frequency, hz ripple rejection, db figure 20. ripple rejection; vin=3.3v, vout=1.8v (adj.), iload=200ma application information: continued
8 apr 20-07 rev b spx1117 800ma low dropout voltage regulator ? 2007 sipex corporation output voltage the output of the adjustable regulator can be set to any voltage between 1.25v and 15v. the value of v out can be quickly approximated using the formula v out =1.25 *(r 1 + r 2 )/r 1 . a small correction to this formula is required depending on the values of resistors r 1 and r 2 , since the adjustable pin current (approx 50 a) flows through r 2 . when i adj is taken into ac - count, the formula becomes v out = v ref (1+ (r 2 /r 1 )) + i adj * r 2 , where v ref =1.25v. layout considerations parasitic line resistance can degrade load regu - lation. in order to avoid this, connect r 1 directly to v out as illustrated in figure 25. for the same reason, r 2 should be connected to the negative side of the load. figure 21. current source figure 22. typical adjustable regulator load adj spx1117 v in c 1 out in 4.7 f c 2 i out r 1 v ref r 1 i out = + v out in out i a d j spx1117 c 1 r 1 r 2 v out v in c 2 v out =v ref (1+r 2 /r 1 ) +i adj r 2 v ref 50 a adj 4.7 f + application information: continued pc board topside copper backside copper thermal resistance junc. to amb. mm 2 mm 2 mm 2 c/w 2500 2500 2500 46 2500 1250 2500 47 2500 950 2500 49 2500 2500 0 51 2500 1800 0 53 1600 600 1600 55 2500 1250 0 58 2500 915 0 59 1600 600 0 67 900 240 900 72 900 240 0 85 table 1
