7 jun 5-07 rev e spx3819 500ma, low noise ldo voltage regulator ? 2007 sipex corporation the spx3819 requires an output capacitor for device stability. its value depends upon the application circuit. in general, linear regulator stability decreases with higher output currents. in applications where the spx3819 is sourcing less current, a lower output capacitance may be sufficient. for example, a regulator outputting only 10ma, requires approximately half the capacitance as the same regulator sourcing 150ma. bench testing is the best method for determining the proper type and value of the capacitor since the high frequency characteristics of electro - lytic capacitors vary widely, depending on type and manufacturer. a high quality 2.2 f alumi - num electrolytic capacitor works in most appli - cation circuits, but the same stability often can be obtained with a 1 f tantalum electrolytic. with the spx3819 adjustable version, the mini - mum value of output capacitance is a function of the output voltage. the value decreases with higher output voltages, since closed loop gain is increased. typical applications circuits a 10nf capacitor on the byp pin will signifi - cantly reduce output noise, but it may be left unconnected if the output noise is not a major concern. the spx3819 start-up speed is in - versely proportional to the size of the byp capacitor. applications requiring a slow ramp- up of the output voltage should use a larger c byp . however, if a rapid turn-on is necessary, the byp capacitor can be omitted. the spx3819? internal reference is available through the byp pin. figure 1 represents a spx3819 standard appli - cation circuit. the en (enable) pin is pulled high (>2.0v) to enable the regulator. to disable the regulator, en < 0.4v. the spx3819 in figure 2 illustrates a typical adjustable output voltage configuration. two resistors (r 1 and r 2 ) set the output voltage. the output voltage is calculated using the formula: v out = 1.235v x [ 1 + r 1 /r 2 ] r 2 must be > 10 k ? and for best results, r 2 should be between 22 k ? and 47k ? . application information + + gnd en byp (opt.) enable may be tied directly to v in spx3819 1 2 3 4 5 v in v out top view + + gnd en hi-on lo-off spx3819 sot-23 1 2 3 4 5 v in v out r1 r2 top view figure 1. standard application circuit figure 2. typical adjustable output voltage configuration

sipex faq ? 2006 sipex corporation for further assistance, contact sipex technical support: sipexsupport@sipex.co m solved by tm spx3819: faq part number: spx389 date: sept4-06 question: assuming a nominal load of 250ma @ 3v dc, how much ground current will be consumed? with a 6v input, will the part even get warm? how about with a 2v input? answer: the spx38 9 data sheet contains a graph of ground current vs load current for your review. also we suggest that you download the thermal considerations application note which includes a few example calculations from the spx389: http://www.sipex.com/fles/applicationnotes/ldothermal.pdf the linear regulator heat calculator could also prove helpful: http://www.sipex.com/fles/applicationnotes/thermalcalculator.xl s customer bench testing is strongly recommended using intended application circuit to ensure proper operation. question: is this part similar to your sp6203 cmos part in the above regard? or, is it like a conventional regulator (lm7805) where the excess voltage turns into heat? answer: all ldos will transfer most of its energy to heat. to minimize this temperature rise keep the input to output voltage difference slightly above dropout voltage. see the applications note mentioned above. question: can ceramic capacitors be used on the output? answer: ceramic capacitors may be used for this part. for tantalum or aluminum electrolytic types, keep the equivalent series resistance (esr) as small as possible. question: considering the psrr is 70db, what is a better strategy for fltering the 60hz ripple from the wall cube? a big high voltage electrolytic on the input or a smaller, low voltage ceramic on the output? or, a combination of both? answer: a small common mode choke would be best for fltering this ripple. variations / combinations of input capacitance might also help but bench testing would be required.
sipex faq 2 ? 2006 sipex corporation for further assistance, contact sipex technical support: sipexsupport@sipex.co m question: is there any practical limit to how much capacitance is used on the input or output? answer: input and output capacitance may be increased without limit. question: it would appear, from the data sheet, increasing the bypass capacitor above 0.0 uf has little improvement in terms of noise. we use a special low esl/esr 0.1uf ceramic as standard for rf bypassing. any concerns about using these on your bypass pin as well? answer: if the bypass pin is to be used a 0nf ceramic capacitor is suggested. you may also use the value / type mentioned. the only concern with the bypass feature is that startup time is increased. if startup time is a concern then the bypass pin should be kept open. different values of bypass capacitor will result in different startup times. question: a portion of this application involves modulating a ir led with a 400khz signal having a 50% duty cycle or less. assumming a drive level of amp per 25s pulse, will your device even see this as an overload and go into current limiting? if so, should a large electrolytic be employed on the output? answer: this is a little diffcult to answer not knowing how you plan on modulating the led. if the enable input is used for modulation it is possible that the device may not react fast enough to provide an output. this is very much true if the bypass pin is used. if the output load exceeds the current limit trip point then the output will be turned off to protect the device. however. if the output is always on and modulation is done with some external circuitry, then adding extra capacitance to the output could satisfy the current demand of the led so as not to cause current limit activation. question: this part is quite attractive in terms of its reverse battery protection feature. do you have any other more current/better alternatives? answer: for a 500ma output current device this is the best sipex offers for package size and performance. check our ldo products page for all of sipex ldo offerings. http://www.sipex.com/productselector.aspx?family=lowdropou t
sipex faq 3 ? 2006 sipex corporation for further assistance, contact sipex technical support: sipexsupport@sipex.co m question: if a 3v battery pack was connected to the output, without a wall wart connected to the input, would any current fow back through the device? answer: the datasheet does not state that this device is operable in a pre-biased output condition; therefore, leakage may occur. question: if the 3v battery pack was connected to the input, what would the output voltage be with a 250ma load? answer: if the input voltage is above dropout voltage then the part will regulate for the entire output current range up to 500ma.
