TCR2LF18,LM(CT) 是东芝(TOSHIBA)提供的一款低静态电流、固定输出的线性稳压器(LDO),封装为小型 SMV(SOT-25-5),面向便携、电池供电与空间受限的电子系统。器件输入电压上限 5.5V, 输出固定为 1.8V,最大输出电流标称 200mA,并内建过流保护(OCP),工作结温范围为 -40℃ ~ +85℃。
优点:极低静态电流有利于延长电池寿命,小封装适合空间受限应用,内置过流保护提高系统可靠性。
注意事项:在接近最大输出电流时关注压降与功耗带来的温升。输出电容的选型与放置直接影响稳压器稳定性与瞬态响应,使用前请参考完整数据手册以确认电容 ESR 与布局要求。
总结:TCR2LF18,LM(CT) 是一款适合低功耗、空间受限应用的 1.8V 固定 LDO,凭借低 Iq 与小封装在便携设备与局部稳压场景中具有明显优势;在高功耗或大压差场合,应注意热设计或考虑开关电源方案。

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.
