For Automotive 45 V Input
200 mA Fixed Output LDO Regulators
BD4xxS2-C Series
General Description
Features
◼ Qualified for Automotive Applications
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.

3.3 V or 5.0 V (Typ)
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.
◼ Enable Input (Only W: Includes Enable Input)
◼ Over Current Protection (OCP)
◼ Thermal Shutdown Protection (TSD)
◼ AEC-Q100 Qualified(Note 1)
◼ Functional Safety Supportive Automotive Products
(Note 1): Grade 1
