LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
PACKAGE OUTLINE
The NJM2391 is low dropout voltage regulators
featuring high precision voltage.
It is suitable for Notebook PCs, PC cards and hard
disks where 3.3V need to be generated from 5V supply.
A small TO-252 package is adopted for the space
saving.
