CJ6211B28F 产品概述
一、器件简介
CJ6211B28F 是江苏长电（CJ）推出的一款固定输出线性稳压器（LDO），输入电压上限为 6V，固定输出 2.8V，最大输出电流可达 500mA。器件采用小尺寸 DFNWB-4L (1×1 mm) 封装，适合空间受限的便携与板上应用。设计目标侧重低压差、低静态功耗与高电源抑制能力，适用于对噪声与稳压精度有较高要求的终端产品。
二、主要电气参数
- 输出类型：固定（2.8V）
- 最大工作电压（VIN）：6V
- 输出电流：最大 500mA
- 压差（Dropout）：55mV @ 100mA（典型条件下）
- 静态电流（Iq）：50µA（典型）
- PSRR：80dB @ 1kHz
- 工作结温范围：0℃ ~ +125℃（Tj）
- 输出极性：正极，单通道输出
三、保护与可靠性
- 具备热关断（Thermal Shutdown）功能，有效防止过热导致的器件损坏；
- 内置短路保护与过流保护，提升系统可靠性并便于异常工况下的自恢复；
- 低静态电流设计利于电池供电系统延长待机时间。
四、封装与布局建议
- 封装：DFNWB-4L (1×1 mm)，适合高密度 PCB 布局；
- 布局建议：输入端与输出端靠近器件引脚放置低 ESR 陶瓷电容以保证稳定性，输入侧建议并联合适旁路电容以抑制高频噪声；器件散热依赖 PCB 铜箔与过孔，需根据最大工作电流与功耗做热设计。
五、典型应用场景
- 便携消费电子（蓝牙设备、手持终端）；
- 低噪声模拟前端与传感器供电；
- 电池供电仪器、IoT 节点与工业控制模块；
- 需要高 PSRR 与低压差的小型电源管理模块。
六、使用注意事项
- 压差标注为 55mV@100mA，实际在更高电流（如 500mA）时压差会增大，应根据系统电压裕量评估输入电压要求；
- 在高功率工作条件下注意热耗散，确保结温不超过规范范围；
- 输出电容类型与容量会影响稳压器稳定性与瞬态响应，建议采用低 ESR 陶瓷电容并参考验证样板测试。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
