H7605-33NR 产品概述
一、产品简介
H7605-33NR 是上海矽朋（Siproin）推出的一款高性能固定输出线性稳压器（LDO），输出电压为 3.3V，采用 SOT-23 小封装设计，面向便携式、低功耗和空间受限的电源管理场景。该器件提供完善的过流保护与短路保护，工作温度范围为 -40℃ 至 +85℃（Ta），具有极低的静态电流，适合电池供电及待机应用。
二、主要特性
- 输出电压：固定 3.3V
- 最大输出电流：300mA
- 静态电流（Iq）：典型 1.5µA（极低待机损耗）
- 压差（Dropout）：190mV @ 100mA（实际压差随电流上升而增大）
- 输出极性：正极输出
- 保护功能：过流保护与短路保护（自动限制并恢复）
- 工作温度：-40℃ ~ +85℃（Ta）
- 封装：SOT-23，单通道设计
三、电气性能要点
H7605-33NR 属于低压差线性稳压器，当输出电流处于中等负载（例如 100mA）时，典型压差仅 190mV，可在较低输入-输出差压下保持稳压输出。静态电流 1.5µA 极大降低了待机能耗，适合长时间待机或休眠频繁的系统。需要注意的是，在接近最大输出电流 300mA 时，压差与功耗会显著增加，应按实际工况评估输入电压裕量与散热条件。
四、保护与可靠性
器件内置过流保护与短路保护，当负载异常时可自动限制输出电流以保护芯片与外围电路。推荐在产品设计中配合合理的输入滤波和熔断/保险元件以提高系统可靠性。工作环境温度覆盖工业级常用范围，适合多数嵌入式与消费电子设备。
五、封装与热管理
SOT-23 小封装便于空间受限的 PCB 布局与量产贴片。由于为线性稳压器，器件功耗等于（VIN - 3.3V）× IOUT，需在高电流或较大压差工况下关注热耗散并采取相应的散热或电路降压措施（例如减小输入电压、分摊负载或采用更大铜箔面积散热）。
六、应用建议
- 便携式和电池供电设备（传感器节点、可穿戴设备）
- MCU、射频模块及传感器的 3.3V 供电
- 工业与消费类低功耗终端
- 在布局上建议：输入/输出电容靠近引脚放置；输出侧使用低 ESR 陶瓷电容（典型 1µF10µF）以保证系统稳定；输入侧也建议加 1µF10µF 去耦器件以抑制瞬态。
H7605-33NR 以其低静态电流、小封装和完整保护特性，为对尺寸与功耗敏感的 3.3V 电源设计提供了可靠且经济的解决方案。若需更详细的引脚定义、电气特性曲线或评价板资料，可联系供应商或查阅器件数据手册。

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.
