General 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 6.5 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 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.
