Product Summary

The BD3005HFP-TR low bias current regulator and watchdog timer features a high 50 V breakdown voltage and is compatible with on-board vehicle microcontrollers. It offers an output current of 500 mA while limiting bias current to 80 μA (Typ.). The series supports the use of ceramic capacitors as output phase compensation capacitors.The reset detection voltage can be changed by connecting a resistor to the Vs pin. The BD3005HFP-TR watchdog timer can be switched on and off using the INH pin input logic.
