com 2ch Low Dropout Voltage Regulator with Reset GENERAL DISCRIPTION The NJM2810 is a 2ch low dropout voltage regulator with reset function.
It provides up to 150mA/100mA as output current, and the reset function monitors individual voltage through VDET terminal with 1% accuracy.
It is suitable for local power supply for small micro controller and other logic applications.
