●General Description

The BD4xxM5 series are low quiescent regulators

featuring 45 V absolute maximum voltage, and output

voltage accuracy of ±2 (3.3 V or 5 V: Typ.), 500 mA

output current and 38 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 enables the device and

“LOW” at the CTL disables the device.

(Only W: Includes Enable Input).

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.

BD450M5WFPJ-CZE2屬于集成電路（IC） > 線性 + 開關穩(wěn)壓器。羅姆半導體集團制造生產的BD450M5WFPJ-CZE2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換為熱量。對于大多數應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。
