HT7533 是 GOODWORK(固得沃克)推出的一款单通道、固定输出的低压差线性稳压器(LDO),输出电压为 3.3V,最大输出电流为 100mA。器件采用 SOT-23 小封装,工作温度范围为 -40℃ 至 +85℃(Ta)。本器件以超低静态电流与极小压差为显著特点,适合电源空间受限且对待机功耗敏感的系统。
关键参数一览
线性稳压器的耗散功率由 Pd = (Vin - Vout) × Iout 决定。举例说明:若输入为 5V,输出 3.3V,差压 1.7V,在满载 100mA 时器件功耗约为 0.17W。SOT-23 封装的散热能力有限,实际允许的输出电流会随封装散热条件和环境温度变化而降低。设计时应注意:
HT7533 提供 SOT-23 小体积封装,适合自动化贴装生产。SOT-23 的小尺寸利于空间受限的终端产品设计,但也对散热提出更高要求。引脚功能通常包括输入(VIN)、输出(VOUT)和地(GND);实际引脚定义请参照厂家完整数据手册以获得准确的引脚排列与推荐外接元件布局。
HT7533 是一款面向低功耗、体积受限应用的 3.3V 固定输出 LDO,凭借 1.5µA 的超低静态电流和极小的轻载压差,特别适合电池供电、长待机的物联网与便携设备。设计时应关注输入电压裕量、输出去耦电容的选择以及 SOT-23 的散热限制,以发挥器件在功耗与尺寸上的优势。欲获得完整电气特性、引脚定义与典型应用电路,请参考 GOODWORK 官方数据手册。

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.
