●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.

BD450M2WEFJ-C屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。羅姆半導(dǎo)體集團(tuán)制造生產(chǎn)的BD450M2WEFJ-C穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負(fù)載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。
