LM22670系列的稳压器是单片集成电路，为降压（降压）开关稳压器，能够驱动高达3A的负载具有优良的线路和负载调节特性的积极功能。 High efficiency (> 90%) is achieved by using a low resistance N-channel MOSFET. The series consists of a fixed 5V output and adjustable version.

SIMPLE SWITCHER ® The concept provides an easy-to-use complete design using a minimum number of external components and the WEBENCH of National Semiconductor ® Design tools. WEBENCH of National Semiconductor ® Tools include features such as external component calculations, electrical simulation, thermal simulation, and simple design, build, and board of it. The switching clock frequency is made up of an internal fixed frequency oscillator, which is at 500 kHz. The switching frequency can also be adjusted with an external resistor or synchronized with an external clock up to 1MHz. It can also automatically synchronize multiple regulators sharing the same switching frequency. LM22670系列还具有内置热关断，电流限制和使能控制输入，可以上下调节功率低25μA的静态电流待机状态。
