♠ I-1.5A, i-Voltage ephantsi, i-Lowd Quiscent yangoku ye-LDO Regulator
I-MCP1727 yi-1.5A Low Dropout (LDO) yokulawula umgca onika amandla aphezulu akhoyo kunye nemveliso ephantsi kwiphakheji encinci kakhulu.I-MCP1727 iza kwinguqu esisigxina (okanye ehlengahlengiswayo) ye-voltage ephumayo, kunye noluhlu oluphumayo lwe-voltage ye-0.8V ukuya kwi-5.0V.I-1.5A yesiphumo sangoku samandla, idityaniswe ne-low output voltage capability, yenza i-MCP1727 ibe yinto efanelekileyo yokuzikhethela kwi-sub-1.8V ye-voltage ye-voltage entsha ye-LDO izicelo ezineemfuno eziphezulu zangoku.
I-MCP1727 izinzile isebenzisa i-ceramic output capacitors ebonelela ngokwemvelo ngengxolo ephantsi yokukhutshwa kunye nokunciphisa ubungakanani kunye neendleko zesisombululo sonke somlawuli.Kuphela yi-1 µF yomthamo wemveliso efunekayo ukuzinzisa i-LDO.
Usebenzisa ulwakhiwo lwe-CMOS, umsinga ozolileyo osetyenziswa yi-MCP1727 ukholisa ukuba ngaphantsi kwe-120 µA phezu koluhlu lwamandla ombane lulonke, iyenza ibenomtsalane kwizicelo zekhompyutha eziphathwayo ezifuna imveliso ephezulu yangoku.Xa ucinyiwe, umsinga ozolileyo uthotywa ube ngaphantsi kwe-0.1 µA.
I-voltage ye-scaled-down output ijongwe ngaphakathi kwaye i-power good (PWRGD) imveliso inikezelwa xa imveliso ingaphakathi kwe-92% yommiselo (eqhelekileyo).I-capacitor yangaphandle ingasetyenziswa kwi-CDELAY pin ukulungisa ukulibaziseka ukusuka kwi-200 µs ukuya kwi-300 ms.
I-overtemperature kunye ne-short circuit current-limiting inika ukhuseleko olongezelelweyo lwe-LDO ngexesha leemeko zempazamo zenkqubo.
