♠ TPS74401 3.0-A, Ultra-LDO oo leh Soft-Start Programmable
Nidaamiyeyaasha tooska ah ee TPS74401-hooseeya (LDO) ayaa si sahlan loo isticmaali karo xal maareyn awood adag oo kala duwan oo codsiyo ah. Barnaamijka la adeegsan karo ee bilowga jilicsan wuxuu yareeyaa walbahaarka isha tamarta isagoo yareynaya qulqulka firfircoonida hadda ee bilowga. Bilawga jilicsan waa monotonic oo si fiican ugu habboon in lagu xoojiyo noocyo badan oo kala duwan oo soo-saareyaal ah iyo wareegyo isku-dhafan oo gaar ah (ASICs). Wax-soo-gelinta awood-siinta iyo soo-saarka awoodda-wanaaggu waxay oggolaataa isku-dabbasho sahlan oo leh xeer-ilaaliyeyaal dibadda ah. Dabacsanaantan dhamaystiran waxay u ogolaanaysaa isticmaaluhu in uu habeeyo xal buuxinaya shuruudaha isku xigxiga ee barnaamijka gate arrayys (FPGAs), soo-saareyaasha signalada dhijitaalka ah (DSPs), iyo codsiyada kale ee leh shuruudaha bilawga gaarka ah.
Tixraaca saxda ah iyo cod-weyneeye khaladku waxa uu keenaa saxnaanta 1% culayska, xariiqda, heerkulka, iyo habka. Qoyska TPS74401 ee LDOs waa xasiloon la'aanteed capacitor ama wax soo saarka dhoobada. Qoyska qalabka ayaa si buuxda loogu qeexay TJ = -40°C ilaa 125°C. TPS74401 waxaa lagu bixiyaa laba xirmo oo 20-pin ah oo VQFN ah oo yar yar (5-mm × 5-mm RGW iyo 3.5-mm × 3.5-mm RGR xirmo), taasoo soo saarta cabbirka guud ee is haysta. Codsiyada u baahan daadinta tamarta dheeraadka ah, xirmada DDDPAK (KTW) sidoo kale waa la heli karaa.
