HT7130S 是友台半导体(UMW)推出的一款低功耗、低压差固定输出线性稳压器(LDO),采用 SOT-23 小型封装,面向对静态电流和噪声有严格要求的便携与工业电子应用。该器件输出电压为固定 3.0V,最高工作电压可达 30V,最大输出电流 100mA,工作环境温度范围 -25℃~+70℃(Ta),具有良好的电源净化能力和使用灵活性。
HT7130S 在 SOT-23 封装下热阻受限。稳压器耗散功率等于 (VIN - 3.0V) × IOUT。在 VIN 接近 30V 且 IOUT 为 100mA 时,器件功耗可达约 2.7W,此类条件下 SOT-23 封装难以散热,建议:
HT7130S 适用于一般工业温度范围内的应用,建议在设计阶段进行热仿真与系统级的耐久性测试,验证在预期输入电压、负载和环境温度下的长期可靠性。特别在高压差大电流工况下,应做好热管理与过流保护设计。
总结:HT7130S 以超低静态电流、固定 3.0V 输出和高达 30V 的输入耐受性,满足对低功耗、小体积和中等电流供电要求的系统。合理的外部电容选择与热设计能显著提升其在实际应用中的性能与可靠性。

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.
