RT9013-28GB 产品概述
一、产品简介
RT9013-28GB 是一款单通道、固定输出的线性低压差稳压器（LDO），输出电压为 2.8V，适用于对噪声与电源纹波有较高要求的小型系统。器件工作温度范围为 -40℃ 至 +85℃（Ta），封装为常用的 SOT-23-5，便于在空间受限的便携和嵌入式设备中应用。产品带有使能（EN）引脚，便于系统级电源管理与快速上电/关断控制。
二、主要特性
- 固定输出：2.8V，单通道输出。
- 工作电压：输入端最高 7V（设计参数）。
- 静态电流（Iq）：仅 60µA，适合低功耗电池供电系统。
- 输出电流：最大可达 500mA，满足多数中等负载需求。
- 压差特性：100mV @ 100mA；300mV @ 200mA，低压差设计利于低压差应用（更高电流下压差会相应上升）。
- PSRR：70dB @ 1kHz，有效抑制电源纹波对敏感电路的干扰。
- 输出噪声：典型 50µVrms，可用于噪声敏感的模拟或射频前端供电。
- 输出极性：正极输出。
三、典型应用
- 便携式设备与电池供电系统（因低静态电流适合待机节能）。
- 模拟与射频前端供电（高 PSRR、低噪声优势明显）。
- 传感器与数据采集电路的局部稳压。
- 工业及消费电子小型模块电源管理。
四、设计与注意事项
- 热耗散：当输入接近 7V、输出 2.8V 且负载接近 500mA 时，功耗可达 (7−2.8)V×0.5A ≈ 2.1W，需注意封装热阻与 PCB 散热，增大铜箔面积或加散热措施以避免热关断。
- 输出电容：为保证稳态与瞬态响应，建议在输出端采用低 ESR 陶瓷电容并靠近输出引脚布置，具体容量与 ESR 参照评估与实测验证。
- 使能控制：EN 引脚用于外部使能/关断控制，可实现系统级电源管理；上电/关断顺序应注意避免输入端出现瞬态对后级敏感电路的冲击。
- 负载与调试：由于压差随电流上升而增加，设计时应根据实际最大负载评估输入电压裕量与热预算。
五、封装与采购信息
- 品牌：TECH PUBLIC（台舟电子）
- 封装：SOT-23-5，适合标准贴片工艺。
RT9013-28GB 适合需要低噪声、高 PSRR 与紧凑封装的中等电流稳压场合，在系统设计时请综合考虑热管理与输出电容选择以获得最佳性能。

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.
