MC34268DR2集成電路（IC）的特殊用途穩(wěn)壓器規(guī)格書PDF中文資料

MC34268DR2屬于集成電路（IC）的特殊用途穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC34268DR2特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換，適用于特定的復(fù)雜應(yīng)用。因此，各種產(chǎn)品特性集差異較大，包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動機(jī)管理等。

The MC34268 is a medium current, low dropout positive voltage regulator specifically designed for use in SCSI–2 active termination circuits. This device offers the circuit designer an economical solution for precision voltage regulation, while keeping power losses to a minimum. The regulator consists of a 1.0 V dropout composite PNP/NPN pass transistor, current limiting, and thermal limiting. These devices are packaged in the 8–pin SOP–8 and 3–pin DPAK and SOT–223 surface mount power packages.

Applications include active SCSI–2 terminators and post regulation of switching power supplies.
