APPLICATION HINTS EXTERNAL CAPACITORS A 1.0μF (orgreater)capacitorisrequiredbetween theoutputand groundforstabilityatoutputvoltagesof5V or more.At loweroutputvoltages,more capacitanceisrequired.Withoutthiscapacitorthepartwilloscillate.Most typesoftantalumor aluminum electrolyticswork finehere;even filmtypeswork butare notrecommended for reasonsofcost.Many aluminum electrolyticshave electrolytesthatfreezeatabout−30°C, so solidtantalumsare recommended foroperationbelow−25°C. The importantparametersofthecapacitorarean ESR ofabout5 Ω or lessand a resonantfrequencyabove 500 kHz.The valueofthiscapacitormay be increasedwithoutlimit. At lowervaluesofoutputcurrent,lessoutputcapacitanceisrequiredforstability.The capacitorcan be reduced to0.33μF forcurrentsbelow10 mA or0.1μF forcurrentsbelow1 mA. Usingthe8-pinversionatvoltagesbelow 5V runstheerroramplifieratlowergainsso thatmore outputcapacitanceisneeded.Fortheworst-casesituation ofa 100 mA loadat1.23Voutput(OutputshortedtoFeedback)a 3.3μF (orgreater)capacitorshouldbe used. Unlikemany otherregulators,theLP4950C willremainstableand inregulationwithno loadinadditiontothe internalvoltagedivider.ThisisespeciallyimportantinCMOS RAM keep-aliveapplications.When settingthe outputvoltageoftheLP4951C versionwithexternalresistors,a minimum loadof1μA isrecommended. A 0.1μF capacitorshouldbe placedfromtheLP4950C/LP4951C inputtogroundifthereismore than10 inches ofwirebetween theinputand theAC filtercapacitororifa batteryisused as theinput. Straycapacitanceto the LP4951C Feedback terminal(pin7) can cause instability.Thismay especiallybe a problemwhen usinghighvalueexternalresistorstosettheoutputvoltage.Adding a 100pF capacitorbetween Outputand Feedback and increasingtheoutputcapacitortoatleast3.3μF willfixthisproblem. ERROR DETECTION COMPARATOR OUTPUT The comparatorproducesa logiclow outputwhenever theLP4951C outputfallsoutofregulationby more than approximately5%. Thisfigureisthecomparator'sbuilt-inoffsetofabout60 mV dividedby the1.235reference voltage.(See to the blockdiagram inthe frontof the datasheet.)Thistriplevelremains“5% below normal” regardlessof the programmed outputvoltageof the 4951C. For example,the errorflagtriplevelistypically 4.75V fora 5V outputor11.4V fora 12V output.The outofregulationconditionmay be due eithertolow input voltage,currentlimiting,orthermallimiting. Figure36 below givesa timingdiagram depictingthe ERROR signaland the regulatedoutputvoltageas the LP4951C inputisramped up and down. The ERROR signalbecomes valid(low)atabout1.3Vinput.Itgoes high at about 5V input(theinputvoltageat which VOUT = 4.75V).Since the LP4951C's dropoutvoltageisload- dependent(seecurveintypicalperformancecharacteristics),theinputvoltagetrippoint(about5V) willvarywith theloadcurrent.The outputvoltagetrippoint(approx.4.75V)does notvarywithload.

LP4950C-5V,LP4951C SNVS208C –SEPTEMBER 2002–REVISED APRIL 2013 www.ti.com The errorcomparatorhas an open-collectoroutputwhich requiresan externalpullupresistor.Thisresistormay be returnedto the outputor some othersupplyvoltagedependingon system requirements.In determininga valueforthisresistor,notethatwhiletheoutputisratedtosink400μA,thissinkcurrentadds tobatterydrainina low batterycondition.Suggested valuesrange from 100k to1 M Ω.The resistorisnotrequiredifthisoutputis unused. *When VIN ≤ 1.3V,theerrorflagpinbecomes a highimpedance,and theerrorflagvoltagerisestoitspull-upvoltage. UsingVOUT as thepull-upvoltage(seeFigure37),ratherthanan external5V source,willkeep theerrorflagvoltage under1.2V(typ.)inthiscondition.The usermay wishtodividedown theerrorflagvoltageusingequal-valueresistors (10kΩ suggested),toensurea low-levellogicsignalduringany faultcondition,whilestillallowinga validhighlogic levelduringnormaloperation. Figure36. ERROR Output Timing PROGRAMMING THE OUTPUT VOLTAGE (LP4951C) The LP4951C may be pin-strappedfor5V usingitsinternalvoltagedividerby tyingthepin1 (output)topin2 (sense)pinstogether,and alsotyingthepin7 (feedback)and pin6 (VTAP )pinstogether.Alternatively,itmay be programmed forany outputvoltagebetween its1.235V referenceand its30V maximum rating.As seen in Figure37,an externalpairofresistorsisrequired. The completeequationfortheoutputvoltageis (1) where VREF isthenominal1.235referencevoltageand IFB isthefeedbackpinbiascurrent,nominally−20 nA. The minimum recommended load currentof 1μA forcesan upper limitof 1.2 M Ω on the valueof R 2, ifthe regulatormust work withno load(a conditionoftenfound inCMOS instandby).IFB willproduce a 2% typical errorinVOUT whichmay be eliminatedatroom temperatureby trimmingR 1.For betteraccuracy,choosingR 2 = 100k reducesthiserrorto 0.17% whileincreasingthe resistorprogram currentto 12μA. Since the LP4951C typicallydraws 60μA atno loadwithPin2 open-circuited,thisisa smallpricetopay.

Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
