... Another regulator characteristic that is noteworthy is that sta- bility decreases with higher output currents. This sensible fact has important connotations. In many applications, the LM2931 is operated at only a few milliamps of output current or less. In such a circuit, the output capacitor can be further reduced in value rough estimation, a circuit that is re- ...
