General Description

The BUxxJA3DG-C series are linear regulators designed

as low current consumption products for power supplies in

various automotive applications.

These products are designed for up to 6.5 V as an absolute

maximum voltage and to operate until 300 mA for the

output current with low current consumption 37 μA (Typ).

These can regulate the output with a very high accuracy,

±2 . These regulators are therefore an ideal for any

applications requiring a low current consumption.

A logical “HIGH” at the EN pin turns on the device, and in

the other side, the devices are controlled to disable by a

logical “LOW” input to the EN pin.

The devices feature the integrated Over Current Protection

to protect the device from a damage caused by a shortcircuiting

or an overload. These products also integrate

Thermal Shutdown Protection to avoid the damage by

overheating.

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

BU18JA3DG-CTR屬于集成電路（IC） > 線性 + 開(kāi)關(guān)穩(wěn)壓器。羅姆半導(dǎo)體集團(tuán)制造生產(chǎn)的BU18JA3DG-CTR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(wú)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(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開(kāi)關(guān)模式的穩(wěn)壓器，但它們通常更適合對(duì)噪聲高度敏感的應(yīng)用。
