描述
The BD4xxS2-C series are low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5.0V: Typ), 200mA output current and 40µA (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.

EXP-PAD

* N.C. Pin is recommended to short with GND.

* N.C. Pin can be open because it isn’t connected it inside of IC.

* EXP-PAD on the back side is connected to the IC substrate, so it should connect to external ground node.
