HT7550是GOODWORK(固得沃克) 推出的一款固定输出型低压差线性稳压器(LDO),专为低功耗、小负载电流、空间受限的电子系统设计。其核心是在宽输入电压范围内提供稳定的5V输出,同时兼顾极低静态功耗与宽温度适应性,典型应用覆盖:
HT7550的核心参数针对小电流、低功耗场景做了针对性优化,关键指标如下:
HT7550采用SOT-23封装,具有以下设计优势:
HT7550工作温度范围为**-40℃+85℃(Ta),属于工业级温度范围**,相比消费级0℃70℃更具优势:
HT7550应用电路极为简单,无需复杂外围元件,典型电路如下:
示例:为低功耗温湿度传感器(SHT30)供电时,仅需HT7550+2个1μF电容,即可实现30V输入到5V稳定输出,静态电流1.5μA,满足电池供电10年以上需求。
HT7550相比同类LDO产品,核心优势集中在:
综上,HT7550是低功耗、小电流电子系统的理想电源管理方案,尤其适合电池供电的便携/工业设备。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
