BL9161G-28BADRN 产品概述

一、概述

BL9161G-28BADRN 是贝岭(BELLING)推出的一款高性能固定输出线性稳压器,输出电压为 2.8V,最大输出电流 300mA。器件面向空间受限且对噪声、纹波抑制有较高要求的便携式与嵌入式系统,集成过流保护、使能控制与热关断等可靠性功能,工作温度范围 -40℃ 至 +85℃,适合工业与消费类应用。

二、主要参数

  • 输出类型:固定(2.8V)
  • 工作电压(输入):6V(器件最高工作电压,请参阅数据手册确认输入范围)
  • 输出电流:最大 300mA
  • 压差(Dropout):205mV @ 200mA(低压差性能,有利于低电压差应用)
  • 静态电流(Iq):70µA(低静态电流,适合电池供电系统)
  • 噪声:180µVrms(低噪声输出,适合模拟/ADC/射频前端供电)
  • 电源纹波抑制比(PSRR):-71dB @ 10kHz(优秀的电源噪声抑制能力)
  • 输出极性:正极,单通道输出
  • 工作温度:-40℃ ~ +85℃
  • 封装:DFN1x1-4L

三、特色功能与保护

  • 过流保护(OCP):在负载异常或短路条件下限制输出电流,保护器件与系统负载。
  • 热关断:当结温超限时自动停机并在温度恢复后重启,提高系统可靠性。
  • 使能控制(EN):外部使能脚可实现快速上电/断电控制,利于电源管理与功耗优化。
  • 低噪声、优良 PSRR:-71dB@10kHz 与 180µVrms 噪声表现,适合对噪声敏感的模拟与通信模块。

四、典型应用场景

  • 便携式电子设备与电池供电系统(低静态电流有利于延长待机时间)
  • 传感器、ADC/DAC 参考供电(低噪声、良好 PSRR 有助于提高测量精度)
  • 无线通信前端与射频模块(稳定的低噪声电源可降低相位噪声干扰)
  • 工业控制与嵌入式系统的辅助电源或子系统电源

五、设计与布局建议

  • 输入/输出端建议使用低等效串联电阻(ESR)的陶瓷电容进行去耦(常见取值范围 1µF–10µF),以确保稳压器稳定工作与瞬态响应。
  • 布局时将输入电容与输出电容尽量靠近器件引脚放置,保持走线最短以降低阻抗和干扰。
  • DFN1x1-4L 小封装需通过底部焊盘良好接地并使用足够的 PCB 铜箔面积或散热孔阵列来改善热性能。
  • 使能脚逻辑电平及开启/关闭时序请参考原厂资料,以免产生非预期的开机行为。

六、封装与可靠性

BL9161G-28BADRN 采用 DFN1x1-4L 超小型封装,适合 PCB 面积受限的应用;封装底部需焊接热焊盘以提升散热性能。器件在 -40℃ 至 +85℃ 的工作温度下能维持规格性能,结合器件内置的过流与热保护机制,可提升整机的安全性与长期可靠性。

总结:BL9161G-28BADRN 是一款面向低噪声、低压差与低功耗场景的单路固定输出 LDO,凭借优秀的 PSRR、低 Iq 与完整的保护功能,适合在便携、测量与通信类终端中作为关键电源模块使用。购买与具体电气参数、引脚定义和推荐外围元件,请以贝岭官方数据手册为准。

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
