NJM2884/A

LOW DROPOUT VOLTAGE REGULATOR

ꢀ GENERAL DESCRIPTION

ꢀ PACKAGE OUTLINE

The NJM2884/A is a low dropout voltage regulator with

ON/OFF control.

Advanced Bipolar technology achieves low noise, high ripple

rejection and low quiescent current.

NJM2884U1/U2

NJM2884ADL3

It delivers up to 5V/500mA output power with the maximum

input voltage of 10V.

The NJM2884/A is suitable for audio/video and PC related

applications.

The “U2” suffix product achieves high P_Dcompared with “U1”

although the same package outline (SOT-89-5) .
