摘　　要：稳压电源是各种实验室必备的仪器,使用频繁。LM317是使用极为广泛且性能优良的三端串联型可调集成稳压器。利用LM317和数字集成芯片的巧妙结合,可构成数控式步进可调直流稳压源,且同步显示输出的挡位数,显示稳定直观,稳压输出取值按照设计需要而设定。本文介绍的数控式步进调压源实现了对输出电压的分挡输出,精度较高,使用方便,具有较高的性价比。DC stabilized voltage power is necessary apparatus in all laboratories,and its utilization ratio is very high. LM317 is a three -end adjustable serious connection integrate device with wide- ranging application and good performance. An adjustable and digital step DC stabilized voltage power made up of digital chip and LM317 is developed. At the same time the grade value is displayed synchronous,and the show is steady and audiovisual. The output values are supposed according to needs. The digital stabilized voltage power in this paper realized to grade output. It is easy to operate, and its precision is higher. In general this DC digital power has better function and lower price.
