AN80LXXRMS Series
Low-drop type positive output voltage regulator IC
s Overview
The AN80LXXRMS series is 0.15 A output low-drop output type positive voltage regulator IC with resetting function. 20 classifications of output voltages, 1.8 V, 1.9 V, 2.0 V, 2.1 V, 2.2 V, 2.5 V, 2.8 V, 2.9 V, 3.0 V, 3.1 V, 3.2 V, 3.3 V, 3.4 V, 3.5 V, 3.6 V, 4.8 V, 4.9 V, 5.0 V, 5.1 V and 5.2 V are available. In addition, it is adopting the surface mounting type package (Mini 5-pin plastic package), so that it is most suited for miniaturization and weight reduction of set equipment.
