General Description

The BD7xxL2EFJ-C, BD7xxU2EFJ-C,

BD7xxL2FP-C, BD7xxL2FP3-C are low quiescent

regulators featuring 50V absolute maximum voltage,

and output voltage accuracy of ±2, 200mA output

current and 6μA (Typ) current consumption. These

regulators are therefore ideal for applications

requiring a direct connection to the battery and a

low current consumption. 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.

Features

Ultra low quiescent current: 6μA (Typ)

Output current capability: 200mA

Output voltage: 3.3 V or 5.0 V (Typ)

High output voltage accuracy: ±2

Low saturation voltage by using PMOS output

transistor.

Integrated overcurrent protection to protect the

IC from damage caused by output

short-circuiting.

Integrated thermal shutdown to protect the IC

from overheating at overload conditions.

Low ESR ceramic capacitor can be used as

output capacitor.

BD733L2EFJ-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BD733L2EFJ-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(gè)最小量，并且在工作時(shí)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。
