RT9078-18GQZ 是 RICHTEK(立锜)推出的一款低压差、低噪声固定输出线性稳压器(LDO),输入电压最高支持至 5.5V,输出为固定 1.8V,最大输出电流 300mA。器件集成过热保护与过流保护,并带有使能(EN)功能,适用于对噪声、PSRR 和静态功耗有较高要求的便携与消费类电子产品。
RT9078-18GQZ 采用 ZQFN-4(1×1mm)超小封装,适合对 PCB 面积要求严格的应用。由于封装体积小,芯片的热阻相对较高,设计时需注意功耗计算与 PCB 散热处理:建议在器件底部焊盘与周围铺设散热铜箔并设计合适的过孔,以提高热传导能力,避免长时间大电流工作导致温升触发保护。
该 LDO 非常适合用于:
总结:RT9078-18GQZ 在超小封装下提供了 1.8V/300mA 的可靠输出、极低静态电流与优异的噪声/PSRR 性能,是空间受限且对电源品质有较高要求的便携式应用的理想选择。请参阅厂家规格书以获取详细的外围电容选型、管脚功能与典型应用电路。

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.
