NJM2817
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJM2817 is a low dropout voltage regulator with ON/OFF
control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.
It delivers up to 5V/3A output power with the maximum input
voltage of 8V.
The NJM2817 is suitable for audio/video and digital applications.
