HT7533是钜兴(JUXING) 推出的一款固定输出型线性稳压器(LDO),针对高输入电压转低电压、小电流稳压场景优化,具备低压差、低静态电流、多重保护等核心优势,广泛适配工业、车载、消费电子等领域的电源设计需求。
HT7533属于单通道正极输出LDO,核心定位为高输入电压(最大36V)→固定3.3V输出的小电流稳压器件,最大输出电流250mA,满足多数低功耗/小功率电路的供电需求。其设计聚焦“低功耗+高可靠性”,适合对静态电流敏感的电池供电系统,以及对电源纹波要求严格的精密电路。
HT7533的性能参数精准匹配实际应用痛点,核心参数如下:
HT7533采用SOT-89封装,体积小巧(尺寸约2.9×2.6×1.1mm),引脚为3针(输入IN、输出OUT、地GND),适配贴片自动化生产,适合空间紧凑的设备(如穿戴设备、小型控制板)。封装的散热性能满足小电流场景需求,无需额外散热片,进一步节省成本与空间。
为提升系统稳定性,HT7533内置三重保护机制:
HT7533支持工业级温度范围(-40℃~+85℃@Ta),可在户外低温、车载高温等极端环境下稳定工作,无需额外温控电路。例如,在车载仪表盘、工业传感器节点中,能长期可靠运行,降低系统维护成本。
HT7533的性能与封装优势,使其适配以下场景:
HT7533以“高输入电压+低静态电流+多重保护”为核心竞争力,为电源设计提供了低成本、高可靠的稳压方案,适合对体积、功耗、可靠性有要求的各类电子设备。

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.
