♠ 1.5A, Korantada Hoose, Xakamaynta LDO ee hadda jirta
MCP1727 waa 1.5A Low Dropout (LDO) nidaamiye toos ah kaas oo bixiya danab wax soo saar sare oo hadda iyo mid hooseeya oo xirmo aad u yar ah. MCP1727 wuxuu ku yimaadaa qaab go'an (ama la hagaajin karo) oo wax soo saarka korantada, oo leh kala duwanaansho koronto ah oo ah 0.8V ilaa 5.0V. Awoodda wax-soo-saarka 1.5A ee hadda jirta, oo ay weheliso awoodda korantada wax-soo-saarka hooseeya, waxay MCP1727 ka dhigaysaa doorasho wanaagsan oo loogu talagalay codsiyada korantada-hoosaadka-1.8V ee LDO-ga oo leh baahiyo hadda jira.
MCP1727 waa xasiloon iyadoo la isticmaalayo capacitors wax soo saarka dhoobada oo si dabiici ah u bixiya sawaxanka wax soo saarka hoose hoosna u dhigaya cabbirka iyo qiimaha xalinta guud. Kaliya 1 µF ee awoodda wax soo saarka ayaa loo baahan yahay si loo dejiyo LDO.
Isticmaalka dhismaha CMOS, hadda quescent ee uu isticmaalo MCP1727 wuxuu caadi ahaan ka yar yahay 120 µA marka loo eego tirada korantada oo dhan, taasoo ka dhigaysa mid soo jiidasho leh codsiyada xisaabinta la qaadan karo ee u baahan wax soo saarka hadda jira. Marka la xidho, hadda waxa la dhimayaa wax ka yar 0.1 µA.
Korontada wax-soo-saarka ee hoos-u-dhaca ayaa gudaha lagu kormeeraa oo wax-soo-saarka korantada wanaagsan (PWRGD) ayaa la bixiyaa marka wax-soo-saarku uu ku jiro gudaha 92% ee qaanuunka (caadiga ah). Capacitor dibadda ah ayaa loo isticmaali karaa biinka CDELAY si loo hagaajiyo daahitaanka laga bilaabo 200 µs ilaa 300 ms.
Heerkulka xad-dhaafka ah iyo xaddidaadda wareegga gaaban waxay siisaa ilaalin dheeraad ah LDO inta lagu jiro xaaladaha cilladda nidaamka.
