MC34268集成电路（IC）的特殊用途稳压器规格书PDF中文资料

MC34268属于集成电路（IC）的特殊用途稳压器。由安森美半导体制造生产的MC34268特殊用途稳压器该系列产品用于电源控制、某种形式的转换，适用于特定的复杂应用。因此，各种产品特性集差异较大，包括空燃比传感器接口、汽车交流发电机电压调节、DDR 端接、液体透镜控制、摩托车转向信号控制、热电 (peltier) 冷却器控制、压电触觉控制、阀门控制、小型发动机管理等。

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.
