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.
