This device excellent choice for use in battery powered. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life. The LM2931 features very low quiescent current (100㎂ Typ.) and very low drop output voltage (Typ. 60㎷ at light load and 300㎷ at 100㎃). This includes a tight initial tolerance of 0.5% Typ., extremely good load and line regulation of 0.05% Typ., and very low output temperature coefficient. The LM2931 fixed-voltage and andjustable regulators is offered in 3-pin TO-92 package compatible with other fixed regulator.
