General Description
The BD4xxS2-C series are low quiescent regulators
featuring 45 V absolute maximum voltage, and output
voltage accuracy of ±2 % (3.3 V or 5.0 V: Typ), 200 mA
output current and 40 μA (Typ) current consumption.
These regulators are therefore ideal for applications
requiring a direct connection to the battery and a low
current consumption.
A logical “HIGH” at the CTL pin enables the device and
“LOW” at the CTL pin not enables the device.
(Only W: Includes switch)
Ceramic capacitors can be used for compensation of the
output capacitor phase. Furthermore, these ICs also
feature overcurrent protection to protect the device from
damage caused by short-circuiting and an integrated
thermal shutdown to protect the device from overheating
at overload conditions.

Applications
■ Body
■ Audio System
■ Navigation System, etc.
