Portable mobile terminal power supply

The utility model discloses a portable terminal power supply which is characterized in that a battery pack is respectively connected with an LDO (Low Drop Output) linear regulator and a DC-DC convertor by a battery monitoring circuit, the LDO linear regulator is connected with a radio frequency plate, and the DC-DC convertor is respectively connected with an FPGA (Field Programmable Gate Array) plate and an ARM (Advanced RISC Machines) plate. The portable mobile terminal power supply has the advantages of long time for continuous use, large current output due to multiple groups of voltage, extremely low noise and ripple wave and small volume as well as light weight.
