集成电路电压调整器的使用正在与日俱增。LM100就是最初的一种,已被广泛应用。设计时考虑多用性,这种电路可作为线性调整器,开关调整器,并联调整器,或甚至作为电流调整器。输出电压可以用一对外加电阻调节在2V～30V,集成电路的工作,其未被调整的输入电压可以达到7伏。集成电路扦件的损耗范围限制了输出电流,小于20ma,但是若外加外部晶体管,就能得到超过5A的电流。参考文献叙述了集成电路的广泛应用。 但少数用户提出LM100在某些应用中不能满意地进行调整。而且用LM100也很难做到在最坏情况下得到满意的负载调整。因而促使我们研制一种新型的集成电路调整器LM105,除了为改善调整之目的而附加特殊的增益级外,LM105和LM100相似。在大多数应用中,用LM105代替了LM100。
The use of integrated circuit voltage regulators is growing. LM100 is the first one, has been widely used. Designed for versatility, this circuit can be used as a linear regulator, switching regulator, shunt regulator, or even as a current regulator. Output voltage can be adjusted with a pair of external resistors in the 2V ~ 30V, IC work, the unadjusted input voltage can reach 7 volts. The loss of integrated circuit components limits the output current, less than 20ma, but if the external transistor, you can get more than 5A of current. References describe the widespread use of integrated circuits. However, a few users have suggested that the LM100 can not be adjusted satisfactorily in some applications. And with the LM100 is also very difficult to achieve satisfactory load adjustment in the worst case. As a result, we were able to develop a new type of integrated circuit regulator, LM105. The LM105 is similar to the LM100 with the exception of a special gain stage for tuning purposes. In most applications, LM105 is used instead of LM100.
