ME6214C45M5G 是南京微盟(MICRONE)推出的一款固定输出型低压差线性稳压器(LDO),输出电压为 4.5V,最大输出电流 300mA。器件具有超低静态电流(典型 0.7μA)、过流保护、短路保护并带有使能(EN)引脚,适用于对功耗和体积有严格要求的便携与工业类供电场景。封装为 SOT-23-5,工作温度范围 -40℃ 至 +125℃。
SOT-23-5 小型封装适合面积受限的应用。器件典型引脚包括:IN、GND、OUT、EN(使能)及可选功能引脚。推荐在输入端和输出端靠近芯片引脚放置低 ESR 的陶瓷旁路电容(例如 1μF~10μF),以保证稳压器稳定性与瞬态响应。布局时注意将 GND 回路缩短并布置散热铜箔以提升热性能。
当输入电压接近上限(例如接近 18V)且输出接满载 300mA 时,器件功耗为 (Vin − 4.5V) × Iout,可能达到数瓦量级,这对 SOT-23-5 封装的散热是较大负担。实际应用中应评估最大允许功耗并采取降压、分流、增加散热铜箔或外部热沉等措施,必要时限制输入电压或输出电流以避免过热。器件适用于 -40℃ 到 +125℃ 环境,但长期可靠性需按实际热管理和封装功耗限制来评估。
如需最终设计验证与详细电气参数(压降、瞬态响应、详细引脚定义、典型电路图与曲线),请参考厂商数据手册以获得完整规范和测试条件。

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.
