NJM2881/82
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
NJM2881/82 is a low dropout voltage regulator with ON/OFF
control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.
It is mounted on SOT-23-5 as small package and 1.0碌F ceramic
capacitor is available. Therefore it is suitable for cellular phone,
camcorder, IC decoder, camera, and other portable items.
