This device excellent coice for use in battery-powered application. Futhermore, the quiescent current increases only slightly at dropout, which prolongs battery life. This series of fixed-voltage and adjustable voltage regulators features very low quiescent current (100uA Typ.) and very low drop output voltage (Typ. 60mV at light load 300mV at 100mA). This Include a tight initial tolerance of 0.5% typ, extremely food load and line regulation of 0.05% Typ., and very low output temperature coefficient. This series of fixed-voltage and adjustable regulators is offered in 3-Pin TO-92 package for LM2930 and 8-Pin SOP-8 package for LM2931 compatible with other fixed-voltage regulators.

Note 2 : Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Note 3 : Line regulation is tested at 150℃ for I L=1mA. For I L=100uA and TJ=125℃, line regulation is guaranteed by design to 0.2%. Note 4 : Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 5 : Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current and output load current. Note 6 : Thermal regulation is the change in output voltage at a time T after a change in power dissipation, excluding load or line regulation effects. Specifications are for a 50mA load pulse (1.25W) for T=10ms. Note 7 : VREF≤VO≤(VIN-1V), 2.3V≤VIN≤30V, 100㎂≤IL≤100㎃, TJ≤TJMAX Note 8 : VSHUTDOWN≥2V, VIN≤26V, VO=0, Feed-back pin tied to -XX V Tap.
