Tej yam ntxwv
TA = 25oC, VIN = VEN = 5 V, CIN = 1 μF, COUT = 1 μF, tshwj tsis yog sau tseg. 
Cov ntaub ntawv thov
Input Capacitor
Txwv tsis pub voltage poob rau ntawm cov khoom siv nkag los ntawm kev hloov pauv hauv kev nrawm nrawm thaum hloov pauv, lub capacitor yuav tsum tau muab tso rau ntawm VIN thiab GND. Cov txiaj ntsig siab dua ntawm CIN tuaj yeem siv los txo cov voltage poob rau hauv cov ntawv thov tam sim no.
Cov zis capacitor
Cov zis capacitor yuav tsum tau muab tso rau ntawm VOUT thiab GND tus pin. Lub capacitor tiv thaiv kab mob parasitic board inductance los ntawm kev yuam VOUT hauv qab GND thaum qhov hloov pauv. Lub capacitor tseem tiv thaiv kev thim rov qab inrush tam sim no los ntawm voltage spike uas tuaj yeem ua rau lub cuab yeej puas thaum lub VOUT luv.
Fault Reporting
Thaum kuaj pom qhov dhau-tam sim no, #OC_FLAG qhia qhov txhaum los ntawm kev ua kom LOW.
Tam sim no txwv
Qhov kev txwv tam sim no ua kom ntseeg tau tias qhov tam sim no los ntawm kev hloov pauv tsis pub dhau qhov siab tshaj plaws tus nqi, thaum tsis txwv qhov tsawg kawg nkaus tus nqi. Qhov tam sim no ntawm qhov txwv qhov txwv yog kho tau los ntawm kev xaiv ntawm sab nraud resistor txuas nrog ISET tus pin. Cov ntaub ntawv rau xaiv cov resistor muaj nyob rau hauv seem hauv qab no. Cov cuab yeej ua raws li qhov chaw tas mus li-tam sim no thaum lub thauj khoom rub tawm ntau tshaj li qhov siab tshaj tus nqi teev los ntawm lub cuab yeej kom txog thaum thermal kaw. Cov cuab yeej rov qab yog tias qhov ntsuas kub tuag poob qis dua qhov pib.
Sub-Voltage Kev kaw haujlwm
The Under-Voltage Lockout (UVLO) tua tus tes hloov yog hais tias tus input voltage poob hauv qab qhov kev kaw tseg. Nrog EN tus pin qhib, lub tswv yim voltage nce siab tshaj UVLO qhov pib tso tawm qhov kev kaw tseg thiab ua kom lub qhov hloov pauv.
Muaj tseeb Reverse-Tam sim no thaiv
Qhov tseeb thim rov qab-tam sim no thaiv kev tiv thaiv qhov kev tawm tswv yim tiv thaiv tam sim no ntws los ntawm cov zis tawm mus rau kev tawm tswv yim txawm tias qhov hloov pauv hloov pauv lossis tsis.
Thermal shutdown
Lub thermal kaw tiv thaiv cov tuag los ntawm sab hauv lossis sab nraud generated kub heev. Thaum lub sijhawm kub dhau, qhov hloov pauv tau muab tua. Qhov hloov pauv tau rov pib dua yog tias qhov kub ntawm qhov tuag poob qis dua qhov ntsuas kub.
Teem Caij Muaj Tsawg
Qhov kev txwv tam sim no tau teeb tsa nrog cov resistor sab nraud txuas ntawm ISET thiab GND pins.
Qhov kev txwv tam sim no yog xam raws li hauv qab no:

Layout Guide
Rau kev ua tau zoo tshaj plaws, tag nrho cov kab yuav tsum tau luv li sai tau. Yuav kom ua tau zoo tshaj plaws, cov khoom siv hluav taws xob thiab cov khoom tso tawm yuav tsum tau muab tso rau ze ntawm lub cuab yeej kom txo qis cov txiaj ntsig uas cov kab mob parasitic kab inductance tuaj yeem muaj nyob rau hauv ib txwm ua haujlwm thiab luv luv. Siv cov kab dav dav rau VIN, VOUT, GND pab txo cov kab mob cab hluav taws xob nrog rau cov ntaub ntawv-rau-ambient thermal impedance.
