CMOS Regulator
Monolithic IC MM327 Series
Outline
This IC is a regulator IC that provides ultra-low current consumption (0.8µA), and low input voltage
(V
O
+0.3~6.0V), and has been developed using the CMOS process. Moreover, in addition to characteristics
such as ultra-low current consumption and low dropout voltage, it supports long lifetime of batteries with a
chip enable function.
The mount area is set to 1.10x1.40mm using a surface mount type leadless 4pin package, whichrealizes
microminiaturization.
