BL9161G-33BAURN 线性稳压器产品概述

BL9161G-33BAURN是贝岭(BELLING) 推出的一款超小型固定输出线性稳压器(LDO),采用SC70-5封装,专为空间受限、低功耗需求的电子系统设计。产品具备稳定的3.3V输出、宽环境适应性及多重保护功能,是便携设备、物联网终端及工业小型模块的理想电源选择。

一、核心身份与基础定位

BL9161G-33BAURN属于固定输出型LDO,区别于可调输出LDO,无需外部电阻调节即可输出3.3V固定电压,简化电路设计;同时区别于开关电源,具备低噪声、低纹波特性,适配对模拟信号敏感的应用场景。产品定位为低功耗、小体积、高可靠性的电源管理器件,覆盖便携与工业级双重需求。

二、关键性能参数深度解析

1. 电压与电流特性

  • 输入/输出电压:最大工作电压6V,固定输出3.3V,电压精度满足多数负载的供电要求;
  • 输出电流:最大300mA,可驱动蓝牙模块、传感器等低功耗负载;
  • 静态电流(Iq):典型值70uA,极低静态功耗,显著延长电池供电设备的续航时间;
  • 压差:205mV(300mA负载下),输入电压仅需比输出高205mV即可满负载稳定工作(如输入3.5V时,仍能输出3.3V@300mA),提升了输入电压的适应性。

2. 纹波与噪声控制

  • 电源纹波抑制比(PSRR):-75dB@1kHz,能有效抑制输入电源中的高频纹波,输出电压纯净度高,适配模拟传感器、音频电路等对电源纹波敏感的场景;
  • 输出噪声:180uVrms(典型值),低噪声特性避免对敏感信号的干扰,提升系统信噪比。

三、多重功能特性保障系统可靠性

BL9161G-33BAURN内置三重保护机制,提升系统抗干扰与耐用性:

  1. 过流保护(OCP):负载电流超过额定值时自动限流,防止稳压器及负载短路损坏,故障排除后自动恢复;
  2. 使能控制(EN):具备外部使能引脚,可通过微控制器开关稳压器,无需切断输入电源即可进入低功耗模式,进一步节省系统功耗;
  3. 热关断(TSD):结温超过阈值时自动关断输出,避免过热烧毁,温度下降后自动恢复。

四、超小型封装与典型应用场景

1. 封装优势

采用SC70-5超小型表面贴装封装,尺寸约2.0mm×2.0mm×0.8mm,占用PCB面积极小,适配对空间要求苛刻的便携设备(如智能手环、蓝牙耳机)。

2. 典型应用

  • 智能穿戴:智能手环、手表的电源管理,低功耗+小封装适配紧凑空间;
  • 物联网终端:温湿度、运动传感器节点的电源,低Iq延长电池寿命,稳定输出保障传感器精度;
  • 便携电子:蓝牙耳机、便携式音箱的辅助电源,低噪声提升音频质量;
  • 工业小型模块:户外传感器节点、车载小模块(如胎压监测辅助电路),宽温范围适配恶劣环境。

五、宽温范围适配复杂环境

工作温度范围为**-40℃~+85℃**,覆盖工业级环境温度要求,可在低温(如北方户外冬季)、高温(如车载夏季高温)场景下稳定工作,无需额外散热设计(满负载功耗约0.81W,SC70-5封装可承受)。

总结

BL9161G-33BAURN凭借小体积、低功耗、稳定输出、多重保护及宽温适应性,简化了电源设计流程,提升了系统可靠性与续航能力,是便携设备、物联网终端及工业小型模块的高性价比电源选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
