Description
Applications
Absolute maximum ratings (Ta = 25°C)
Features
*1 Must not exceed Pd.
*2 Reduced by 12.8 mW/°C over 25°C, when mounted on a glass epoxy board (70 mm × 70 mm × 1.6 mm).
The BD3004HFP,BD3005HFP 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.(BD3004HFP)The watchdog timer can be switched on and off using the INH pin input logic.(BD3005HFP)
