Imatronic LDM115G/633/1

That power available at a specified output of a device under specified conditions of operation.

Supply current refers to the input current to an LDO regulator at no load, which flows inside the IC in order to operate. The power consumption of an LDO regulator can be calculated as. (Input Voltage) x (Consumption current of IC itself) + (Input Voltage - Output Voltage) x (Load current)
