OUTLINE

The R5101G Series are microprocessor power management ICs with high accuracy output voltage and detector threshold and with ultra low supply current by CMOS process. Each of these ICs consists of a voltage regulator, a voltage detector and a watchdog timer. Thus, the R5101G Series have the function of a power management for microprocessor, a monitor of the voltage of a power source and a microprocessor supervisor.
