HT7533ST 是国睿(GR)推出的一款高压差线性稳压器(LDO),专为在高输入电压环境下提供稳定、低噪声的 3.3V 直流电源而设计。该器件支持高达 40V 的工作电压,固定输出电压为 3.3V,最大输出电流可达 200mA,输出精度优良(±3%),静态电流仅 2µA,适合对待机功耗敏感且输入电压范围较宽的应用场合。封装为常见的 SOT-23-3,便于小型化设计与量产装配。
HT7533ST 采用 SOT-23-3 小封装,典型引脚功能包含 VIN、GND、VOUT。不同厂商封装引脚编号可能存在差异,设计时请以正式数据手册为准。典型引脚功能(仅供参考):
在布局时建议将引脚处的接地尽量短且直接连接到主地平面,减小回流路径与噪声耦合。
HT7533ST 为需要在高输入电压条件下提供稳定 3.3V 电源且追求低静态功耗、体积小的设计提供了一个可靠的解决方案。凭借 40V 的输入耐受、低压差和 2µA 的静态电流特性,它在汽车、工业和便携设备等多种场景中具有明显优势。为获得最佳性能,请结合正式数据手册中的电气特性、外部器件推荐和热设计要求进行系统级设计与验证。

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.
