Rohm Semiconductor

BD820F5UEFJ-C is a regulator with a high withstand voltage of 45 V. And it integrates a reset (RESET) that monitors its output and a watchdog timer (WDT). The quiescent current is low while the output current is 200 mA. The reset signal is output when the output of the regulator falls below 4.2 V (Typ). The reset delay time and watchdog monitor time can be adjusted by the external capacitor.This IC uses different production line against series model BD820F50EFJ-C for the purpose of improving production efficiency. We recommend using this IC for your new development. Electric characteristics noted in Datasheet does not differ between Production Line. In addition, the data of BD820F50EFJ-C is disclosed for documents and design models unless otherwise specified.

ROHM’s 2.5 A/1.2 MHz step-up switching regulator BD8311NUV generates step-up output including 8 V or 10 V from 4 batteries, batteries such as Li2cell etc. or a 5 V fixed power supply line. This IC allows easy production of small and a wide range of output current, and is equipped with an external coil/capacitor downsized by high frequency operation of 1.2 MHz, built-in 2.5 A rated 80 mΩ Nch FET SW, and flexible phase compensation system on board.
