BL9161G-18BPRT线性稳压器（LDO）产品概述
一、产品基本定位与基础信息
BL9161G-18BPRT是贝岭（BELLING） 推出的一款固定输出型线性稳压器（LDO），采用SOT-23-3小型贴片封装，专为低功耗、对噪声敏感的电路设计，提供稳定的1.8V正极单通道输出，适配中小功率负载的供电需求。
二、核心性能参数解析
该器件的关键参数针对性解决了便携设备的功耗、噪声及电源稳定性问题，具体如下：
- 输入输出基础特性：输入工作电压典型值为6V，固定输出电压1.8V，最大输出电流300mA，可满足多数小型模块（如蓝牙、传感器）的供电功率；
- 纹波抑制能力：电源纹波抑制比（PSRR）达75dB@217Hz——217Hz是射频通信（如蓝牙、LoRa）中常见的干扰频率，该参数可有效过滤输入电源中的纹波，避免干扰后级敏感电路；
- 小压差设计：满负载（300mA）下压差仅205mV，即输入电压≥2.005V（1.8V+205mV）即可稳定输出1.8V，完美适配锂电池放电后期（电压降至2V左右）的场景；
- 低静态电流：静态电流（Iq）仅110μA，远低于传统线性稳压器，大幅降低设备待机功耗，适合长期待机的便携设备；
- 低噪声输出：输出噪声为180μVrms，在模拟电路（如传感器信号调理、射频前端）中可减少噪声干扰，提升信号采集精度。
三、安全保护与可靠性设计
为保障器件及负载安全，内置双重保护机制：
- 过流保护（OCP）：当负载电流超过阈值时自动限制输出电流，防止短路或过载损坏器件，故障排除后自动恢复；
- 热关断（TSD）：当结温过高（如过载、环境温度过高）时，自动关断输出，避免热损坏；温度降至安全范围后，器件自动恢复正常工作，提升长期可靠性。
四、典型应用场景
结合参数优势，该器件适合以下场景：
- 低功耗便携设备：智能手环、智能手表等可穿戴设备的传感器、蓝牙模块供电；
- IoT终端节点：智能家居温湿度传感器、无线门锁控制器、小型环境监测仪的电源模块；
- 模拟信号电路：微型传感器（如加速度计、气压计）的信号调理电路、低功耗射频前端的稳定供电；
- 电池供电系统：纽扣电池、锂电池供电的小型电子设备（如蓝牙遥控器、电子标签），适配电池放电曲线。
五、封装与工作环境
- 封装形式：SOT-23-3小型贴片封装，尺寸约2.9×1.6×1.3mm，体积紧凑，适合高密度PCB设计；
- 工作温度范围：-40℃~+85℃（环境温度Ta），覆盖商业级宽温范围，可满足户外（如智能农业传感器）、室内（如智能家居设备）等多种环境的稳定工作需求。
总结
BL9161G-18BPRT凭借低功耗、低噪声、小压差、宽温范围及紧凑封装的优势，成为1.8V中小功率供电场景的理想选择，尤其适合对功耗和噪声敏感的便携设备、IoT终端及模拟电路模块。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
