They are an excellent choice for use in Battery Powered applications. The LM2931 feature low quiescent current (100 µA Typ.) and low dropout of only 60mV at light loads and 300mV (typ.) at 100mA. The LM2931 has tight initial tolerance of 0.5% typ., extremely good load and line regulation of 0.05% typ. and very low output temperature coefficient. The Bay Linear LM2931 is available as a fixed voltage regulator and as an adjustable regulator in TO-92 and 8SOIC packages. The Bay Linear LM2931 in an 8SOIC package has an adjustable output voltage from 3V to 24V, programmed with a pair of external resistor. The logic compatible shutdown enables the regulator to be switched ON and OFF.
