NJM2806
Low Dropout Voltage
Regulator with Reset
! GENERAL DISCRIPTION The NJM2806 is a low dropout voltage
regulator with reset function. It provides up to 500mA of logic supply, and the reset function monitors input voltage of the
regulator with 1% accuracy. It is suitable for local power supply and reset for small micro controller and other logic chips. !
