♠ TPS7B82-Q1 Izithuthi 300-mA, High-Voltage, Ultra-Low-IQ Low-Dropout Regulator
Kwiinkqubo ezidityaniswe nebhetri yemoto, i-low quiescent current (IQ) ibalulekile ukugcina amandla kunye nokwandisa ubomi bebhetri. I-Ultra-low IQ kufuneka ifakwe kwiisistim ezihlala zisebenza.
I-TPS7B82-Q1 yi-low-dropout linear regulator eyenzelwe ukusebenza nge-wide input-voltage range ukusuka kwi-3 V ukuya kwi-40 V (45-V yokukhusela umthwalo wokulahla). Ukusebenza phantsi ukuya kwi-3 V ivumela i-TPS7B82-Q1 ukuba iqhubeke nokusebenza ngexesha le-cold-crank kunye nokuqala nokuyeka iimeko. Nge-2.7-µA kuphela i-quiescent yangoku eqhelekileyo kumthwalo okhanyayo, esi sixhobo sisisombululo esona sisisombululo sokunika amandla ii-microcontrollers (MCUs) kunye ne-CAN/LIN ii-transceivers kwiinkqubo zokulinda. Isixhobo sibonisa i-short-circuit edibeneyo kunye nokukhusela okugqithisiweyo.
Esi sixhobo sisebenza kumaqondo obushushu akwi-Ambient ukusuka ku-40°C ukuya +125°C kunye namaqondo obushushu obuphakathi ukusuka ku –40°C ukuya +150°C. Ukongeza, esi sixhobo sisebenzisa ipakethe ye-thermal conductive ukwenza umsebenzi ozinzileyo nangona kukho ukuchithwa okubalulekileyo kwisixhobo. Ngenxa yezi mpawu, isixhobo siyilwe njengonikezelo lwamandla kwizicelo ezahlukeneyo zeemoto.
