SGM2041-1.8XG/TR 产品概述
SGM2041-1.8XG/TR 是圣邦微（SGMICRO）推出的一款超低静态电流、低压差固定输出线性稳压器（LDO），输出1.8V、最大输出电流300mA。该器件采用紧凑的 WLCSP-4B (0.7 × 0.7 mm) 封装，适合空间受限的移动与便携式终端、物联网节点和射频/模数前端供电场景。
一、主要性能特点
- 固定输出电压：1.8V，单通道正向输出。
- 最大输出电流：300 mA。
- 最大工作电压（输入电压）：5.5 V（典型系统上限，详见器件规范书）。
- 低压差：130 mV @ 300 mA，适合低压差供电场合。
- 静态电流（Iq）：11 μA，适合对待机功耗敏感的应用。
- 低噪声：9.5 μVrms（典型），有利于模拟和射频电路噪声预算。
- 优良的电源纹波抑制：PSRR = 92 dB @ 1 kHz，便于抑制开关电源噪声。
二、保护与控制功能
- 带使能（EN）引脚，支持外部开关控制与功耗管理。
- 过流保护（OCP）与短路保护（SCP），提高系统可靠性。
- 过热保护（OTP），防止温度异常导致损坏。
三、封装与可靠性
- 封装：WLCSP-4B，尺寸 0.7 mm × 0.7 mm，适配高密度 PCB 布局与小型化产品。
- 工作温度范围：-40 ℃ 至 +125 ℃（Tj），满足工业级温度要求。
- 型号后缀 TR 表示卷带包装（Tape & Reel），便于自动贴片生产线使用。
四、典型应用建议与注意事项
- 适用场景：便携式设备电源、MCU/传感器供电、射频前端低噪声电源、存储器/ADC/DAC 的本地 LDO、无线终端与 IoT 终端。
- 输出电容：器件对输出电容稳定性敏感，建议使用低 ESR 陶瓷电容以保证瞬态响应与稳定性（请参照数据手册中推荐的电容值与布局指南）。
- 散热考量：WLCSP 小尺寸限制了散热能力。在 Vin 较高或持续满载（300 mA）条件下，功耗为 (Vin − 1.8V) × Iout，需评估 PCB 散热路径与热量限制，必要时通过降低输入电压、分配功率或增加热沉/铜箔面积来控制结温。
五、典型规格速览
- 输出电压：1.8 V（固定）
- 最大输出电流：300 mA
- 压差（Dropout）：130 mV @ 300 mA
- 静态电流：11 μA
- 噪声：9.5 μVrms
- PSRR：92 dB @ 1 kHz
- 保护功能：过流、短路、过热、使能控制
总结：SGM2041-1.8XG/TR 以其超低静态电流、低噪声和高 PSRR 特性，适合对功耗与电磁兼容有严格要求的小型便携和工业设备。选型时请结合输入电压范围、热设计与外部电容规格，参考官方数据手册完成最终电路设计与布局。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
