HRT9013-33GB 是华轩阳电子(HXY MOSFET)推出的一款固定输出 3.3V 低压差线性稳压器(LDO),采用 SOT-23-5L 小封装,面向对功耗、噪声与电源抑制有较高要求的便携与嵌入式应用。器件设计注重低静态电流与良好的瞬态响应,适合电池供电或对待机功耗敏感的系统。
HRT9013-33GB 内置过流与短路保护机制,可在异常负载条件下限制输出电流,避免器件与负载损坏。设计时仍建议考虑热限流与功耗管理:当输入为7V、输出3.3V且满载500mA时,器件功耗可达约1.85W,应通过 PCB 散热设计与功率预算进行恰当热管理,以保证长期可靠性与温升控制。
SOT-23-5L 小封装适合空间受限应用,但导热能力有限。建议在 PCB 上预留宽铜箔散热区域(热沉铜)并连接 GND 平面以降低结壳温度;必要时采用多层板和过孔导热方式。典型应用中应按最大结温限制对输出电流进行温度折减。
HRT9013-33GB 在小封装下提供了低静态电流、低噪声与良好 PSRR 的 3.3V 稳压输出,是对空间、功耗与电源质量有综合要求应用的合适选择。若需器件详细典型电路图与 PCB 参考布局,请参照厂家规格书或联系供应商获取完整资料。

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.
