Description

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 6.5V as an absolute maximum voltage and to operate until 300mA for the output current with low current consumption 37µA (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 shortcircuiting 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.
