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 re-
duction of set equipment.
s
Features
