Datasheet
200-mA 3.3-V or 5.0-V Output
LDO Regulators
BD4xxM2-C Series
General Description
Features
The BD4xxM2-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.
