NJM2391 Datasheet, PDF (1/7 Pages) New Japan Radio – LOW DROPOUT VOLTAGE REGULATOR

NJM2391
LOW DROPOUT VOLTAGE REGULATOR
„ GENERAL DESCRIPTION
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.
