●General Description

The BD4xxM2-C / BD4xxU2-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.

BD433M2WFP3-C属于集成电路（IC） > 线性 + 开关稳压器。罗姆半导体集团制造生产的BD433M2WFP3-C稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
