描述
BD433U2EFJ-C是45V耐压、输出电压精度±2%、输出电流200mA、静态电流40μA、输出电压恒定（3.3V）的低静态电流稳压器。本IC非常适合用来降低电池直连系统中的消耗电流。可以启用或禁用输出关闭功能，针对支持该功能的产品，当对CTL引脚施加HIGH电压时，元器件的输出ON；当施加LOW电压时，元器件的输出OFF。输出的相位补偿电容器可使用陶瓷电容器。另外，本IC还内置过电流保护电路，可防止输出短路等导致的IC损坏；内置过热保护电路，可防止IC因过负载状态等导致的热损坏。本系列产品中的BD433M2EFJ-C是为提高生产效率而变更生产线后的型号。在新项目选型时，建议选择该型号。另外，在技术规格书中的保证特性并没有差异。

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.

 Qualified for Automotive Applications

 Wide Temperature Range:

 Wide Operating Input Range:

 Low Quiescent Current:

 Output Current:

-40 °C to +150 °C

3.0 V to 42 V

40 μA (Typ.)

200 mA

 High Output Voltage Accuracy:

 Output Voltage:

±2 %

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

●Packages

 EFJ: HTSOP-J8

●Applications

 Automotive

(body, audio system, navigation system, etc.)

●Typical Application Circuits

 Components externally connected: 0.1 µF ≤ CIN, 10 µF ≤ COUT (Typ.)

*Electrolytic, Tantalum and Ceramic capacitors can be used.
