General Description

The BD9xxM5-C series are linear regulators using the

QuiCurTM 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 500 mA for

the output current with low current consumption 9.5 μA

(Typ). These can regulate the output with a very high

accuracy ±2.0 %. 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 16 V by

an external resistive divider connected to the ADJ pin.

Output shutdown function is integrated in the devices(Note

2). 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.

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) QuiCurTM is a combination of technologies that provides high-speed

load response.
