General Description

The BD9xxN1-C series are linear regulators using the

Nano CapTM topology (Note 1) designed as low current

consumption products for power supplies in various

automotive applications requiring a direct connection to the

battery.

These products are designed for up to 45 V as an absolute

maximum voltage and to operate until 150 mA for the

output current with low current consumption 28 μA (Typ).

These can regulate the output with a very high accuracy

±2.0 .

The output capacitor 100 nF (Typ) or more can be used for

this product series, and it can realize a brilliant transient

characteristic even with small capacitance.

The output voltage line-up are 3.3 V, 5.0 V and Adjustable

type by an external resistive divider. The output voltage

can be adjusted between 1.0 V and 18 V by an external

resistive divider connected to the ADJ pin.

Enable feature is integrated in the devices. A logical “HIGH”

at the EN pin turns on the device, and the devices are

controlled to disable by a logical “LOW” input to the EN pin

(Note 2).

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 and Under Voltage Lock Out to avoid false

operation at low input voltage.

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

(Note 1) Nano Cap? is a combination of technologies which allow stable

operation even if output capacitance is connected with the range of nF unit.

(Note 2) Applicable for product with Enable Function
