KIA7810AF-RTF/PQ 产品概述
一、概述
KIA7810AF-RTF/PQ 是 KEC 出品的一款固定正电压线性稳压器，提供 10V 输出、单通道设计，适用于对噪声和纹波有较高要求的电源前后端稳压。器件内置过流保护和过热保护，工作结温范围宽 (-40℃ 至 +150℃@Tj)，采用表面贴装的 TO-252-2 (DPAK) 封装，便于 PCB 工艺和散热设计。
二、主要参数
- 输出电压：10V（固定）
- 最大输出电流：典型 1.0A 级（压差指标以 1A 时的压差给出）
- 压降（Dropout）：2V @ 1.0A（因此在满载时输入电压至少需 ≥12V）
- 静态电流 (Iq)：4.3mA
- 噪声：80 µVrms（低噪声，适合模拟前端）
- PSRR：55dB @ 120Hz（120Hz 的电源纹波可被衰减约 10^(55/20) ≈ 562 倍；例如 1Vpp 输入纹波约降至 ≈1.8mVpp）
- 保护：过流限流与过热关断
- 工作结温：-40℃ ~ +150℃@Tj
- 封装：TO-252-2 (DPAK)
三、关键特性与保护
器件内置完善的保护机制：当输出短路或过载时，内置电流限制防止大电流损伤；当结温升高到保护门限时进入热关断，待降温后恢复输出。这些特性提高了在非理想工况（短路、散热不足）下的可靠性。较低的静态电流适合效率和待机功耗有要求的设计，较高的 PSRR 与低噪声使其适合对模拟信号敏感的电路。
四、典型应用
适用于工业控制、电源后稳压、模拟电路供电、传感器供电、通信设备与仪器仪表等场合。尤其适合需要 10V 稳定低噪声电源的运放偏置、基准供电或传感器激励电路。
五、热管理与布局建议
- 输入电压在满载时需至少高于输出 2V（1A 条件），建议留有余量以应对纹波与瞬态。
- 输入侧靠近 VIN 焊盘放置 0.1µF 陶瓷去耦并配合 10µF 低 ESR 电解或固态电容以稳定供给；输出侧建议 1–10µF 低 ESR 电容改善瞬态响应与噪声。具体电容值应以器件数据手册为准。
- DPAK 的散热依赖于 PCB 铜箔面积与热过孔，建议在器件底部和散热焊盘处扩大铜箔并使用多层内层散热通道，以降低结壳温升并保证长期可靠性。
- 参考原厂数据手册确认引脚定义与安装方向，避免因焊盘连接错误影响性能或散热。
六、封装与选购
KIA7810AF-RTF/PQ 提供 TO-252-2 (DPAK) 表面贴装形式，适合自动贴装生产。选购时请核对批次、封装标识与原厂数据手册，关注最大输入电压、输出电流在特定工况下的热限流表现。若需更高效率或更小压降，可考虑低压差稳压器 (LDO) 或开关稳压方案作为替代。

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.
