LR6205B28M是乐山无线电(LRC)推出的固定输出型低压差线性稳压器,专为低噪声、低功耗、宽温适应性场景设计,核心输出电压2.8V,持续输出电流500mA,适配电池供电、射频前端、工业传感器等多类应用需求。
LR6205B28M的关键参数围绕“低噪声、低功耗、高稳定性”设计,核心指标如下:
针对217Hz(GSM、蓝牙等射频系统的突发时钟频率)的80dB PSRR,可有效抑制电源纹波对射频收发器、传感器信号链的干扰;40uVrms的低噪声(0.1-10Hz)则能保证模拟电路(如心率传感器、压力传感器)的信号精度,避免噪声引入测量误差。
50uA的典型静态电流(仅为普通LDO的1/5~1/10),在轻载或待机状态下可显著延长电池续航;160mV@150mA的低压差特性,让输入电压接近输出时仍能稳定工作(如单节锂电池3.7V放电至2.9V时,仍可输出稳定2.8V)。
LR6205B28M的性能特性使其适配多类场景:
LR6205B28M的应用电路简单,无需外部复杂元件:
内置保护机制无需额外添加短路/过流保护电路,进一步简化设计。
LR6205B28M凭借低噪声、低功耗、宽温适应性及完善的保护功能,成为电池供电设备、射频电路、工业传感器等场景的优选LDO方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
