SGM2203-3.0YK3LG/TR 是圣邦微(SGMICRO)推出的一款固定输出线性低压差稳压器(LDO),固定输出电压为 3.0V。器件为单路正向输出,封装为 SOT-89-3,适用工作温度范围 -40℃ 至 +85℃。主要规格包括:最大工作电压 36V、输出电流 150mA、静态电流(Iq)仅 4.2µA、在 1kHz 时电源纹波抑制比(PSRR)约 55dB,以及在满载 150mA 时的压差(Dropout)约 2.4V。器件集成过流保护和过热保护,便于系统可靠性设计。
适用于从高电压轨(如 9V/12V/24V)降至 3.0V 的电子设备:工业控制模块、仪表与传感器前端、通信终端模块、某些需要长待机但工作电流不大的便携设备等。注意如果输入电压接近 5V 或电流接近 150mA 时,因压差较大可能无法满足输出要求。
优点:超低静态电流、支持较高输入电压、内置保护、封装小巧。
缺点:在满载时压差较高(限制了在低输入电压下的使用)、最大输出电流仅 150mA,SOT-89 散热受限。
选型建议:若系统需从较高电压稳压至 3.0V 且待机功耗要求严格,同时负载电流不超过中等水平,SGM2203-3.0 是经济且可靠的选择;若工作在低压差或大电流工况,应考虑低压差(LDO)或开关降压方案。
型号:SGM2203-3.0YK3LG/TR,品牌:SGMICRO(圣邦微),封装:SOT-89-3;“-TR”通常表示卷带盘装(Tape & Reel),便于贴片自动化生产。购买和最终设计请参考厂商最新规格书与布局参考电路。

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.
