H7236-1M5R 产品概述
一、产品简介
H7236-1M5R 是上海矽朋（Siproin）推出的一款固定输出线性低压差稳压器（LDO），输入最高可达15V，输出为单通道正电压 3.6V，最大输出电流 400mA。器件封装为 SOT-23-5，适合空间受限的便携与消费类电子应用。
二、主要电气性能
- 输出类型：固定（3.6V）
- 最大输入电压：15V
- 最大输出电流：400mA
- 压降：180mV @ 80mA（压降随负载增加而上升，400mA 时请参考器件曲线）
- 静态电流（Iq）：2µA（极低静态电流，适合电池供电）
- PSRR：40dB @ 1kHz，具备良好的电源纹波抑制能力
- 特性：带使能（EN），过流保护（OCP）
- 工作温度：-40℃ ~ +85℃
- 封装：SOT-23-5
三、功能与保护
H7236-1M5R 提供逻辑控制的使能引脚，可实现电源开关控制与功耗管理；内置过流保护，遇短路或过载时限制输出电流以保护器件与负载。低静态电流设计可显著降低待机功耗，提高电池寿命。
四、典型应用场景
适用于便携式设备、传感器节点、手持终端、消费类电子、微控制器电源轨以及要求低待机电流和中等电流供给的各类系统。40dB@1kHz 的PSRR对中频噪声抑制有明显帮助，适合噪声敏感的模拟前端。
五、布局与外部元件建议
为保证稳压器性能与热散性能，建议：
- 输入端并联陶瓷电容（如0.1–1µF）与适当的滤波电容；
- 输出端使用低ESR陶瓷电容（常见建议值范围 2.2–10µF），并紧贴输出引脚放置；
- 使能端与地之间加入去耦电容或拉电阻以抑制毛刺（具体阈值与连接方式请参照数据手册）；
- SOT-23-5 封装散热有限，若长期高电流工作，请优化铜箔面积与多孔过孔以提高散热。
六、注意事项
- 压差规格以 80mA 为参考，400mA 工作条件下压降与功耗会显著增加，须核查器件热限与实际效率；
- 使能阈值、过流恢复行为及输出电容 ESR 要求等关键参数请在设计前查阅完整数据手册以确认匹配性；
- 在高温或高功耗场景下注意热关断与稳态散热设计，避免进入热限制区域。
七、封装与订购信息
- 品牌：Siproin（上海矽朋）
- 型号：H7236-1M5R
- 封装：SOT-23-5 如需样片、技术规格书或评估板，请联系厂商或授权分销商获取最新资料与支持。
总结：H7236-1M5R 以其 3.6V/400mA 的输出能力、低静态电流与良好 PSRR，适合对待机功耗和电源质量有要求的便携与嵌入式应用。设计时应重点关注输出电容匹配与热管理，以发挥器件最佳性能。

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.
