| Abstract: | GSM modules are now widely adopted for remote data transmission. In the portable and mobile application area, the limita-tion of power supply capacity,high level of ripple noise and huge transient current may damage the system stability.In this article,one5V/600mA power supply solution designed for TC35i GSM module will be discussed,which has been applied in a project and provedto be reliable and effective. |
