BUxxJA3DG-C series  
General Description  
Key Specifications  
The BUxxJA3DG-C series are linear regulators designed  
as low current consumption products for power supplies in  
various automotive applications.  
These products are designed for up to 6.5 V as an absolute  
maximum voltage and to operate until 300 mA for the  
output current with low current consumption 37 µA (Typ).  
These can regulate the output with a very high accuracy,  
±2 %. These regulators are therefore an ideal for any  
applications requiring a low current consumption.  
A logical “HIGH” at the EN pin turns on the device, and in  
the other side, the devices are controlled to disable by a  
logical “LOW” input to the EN pin.

The devices feature the integrated Over Current Protection  
to protect the device from a damage caused by a short-  
circuiting or an overload. These products also integrate  
Thermal Shutdown Protection to avoid the damage by  
overheating.  
Furthermore, low ESR ceramic capacitors are sufficiently  
applicable for the phase compensation.
