Voltage Regulators
AN80LxxRMS Series
Positive output, low dropout voltage regulator (150 mA type)
s
Overview
The AN80LxxRMS series is a 0.15 A, low dropout,
positive voltage regulator with reset function. 20 classifi-
cations 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 pack-
age, so that it is most suited for miniaturization and weight
reduction of set equipment.
