Class A amplifiers vary the large quiescent current in order to generate a varying current in the load, hence they are always inefficient in power terms. In addition, the MCP1810 can be shut down for an even lower 1 nA (typical) supply current draw. Quiescent current Among other important characteristics of a linear regulator is the quiescent current, also known as ground current or supply current, which accounts for the difference, although small, between the input and output currents of the LDO, that is: {\displaystyle I_ … 0000009658 00000 n 0000001746 00000 n Unit .
