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.

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit  
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is  
operated over the absolute maximum ratings.  
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the  
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance and power dissipation taken into  
consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating.  
(Note 1) Do not exceed Pd.  
(Note 2) Applicable for product with Enable Input.  
The start-up orders of power supply (VCC) and the CTL pin do not influence if the voltage is within the operation power supply voltage range.
