XC6223H331MR-G 产品概述
一、概述
XC6223H331MR-G 是 TOREX（特瑞仕）推出的一款低压差线性稳压器（LDO），提供固定 3.3V 输出，最大输出电流 300mA。器件设计侧重于低静态电流与高电源纹波抑制，适用于对噪声和功耗敏感的便携与嵌入式系统。
二、主要特性
- 输出类型：固定 3.3V。
- 工作电压：最高 5.5V（输入电压需高于输出电压加压差以保证稳压，满载时大约需 ≥3.5V）。
- 最大输出电流：300mA。
- 压差（Dropout）：约 200mV @ 300mA，适合低电压差供电场景。
- 静态电流（Iq）：约 100µA，利于电池供电系统延长待机时间。
- PSRR：约 80dB @ 1kHz，具有良好的电源噪声抑制能力。
- 保护功能：过流保护、短路保护、过热保护。
- 带使能端，便于系统电源管理与功耗控制。
- 输出极性：正极；单通道输出。
- 工作温度范围：-40℃ 至 +105℃（Ta）。
三、电气与热设计要点
在设计时需注意输入电压必须高于输出电压加压差（VOUT + Vdrop）以确保 3.3V 输出稳定；当 VIN = 5.5V、VOUT = 3.3V、IOUT = 300mA 时，稳压器功耗约为 (5.5-3.3)*0.3 ≈ 0.66W，需合理考虑封装导热与PCB散热（散热垫、铜箔面积等）。静态电流较低，但在频繁启停或待机模式下仍建议利用使能端管理电源。
四、应用场景
适用于各类移动与便携设备、物联网终端、传感器节点、MCU/FPGA 供电电源、模拟前端与射频电路（得益于较高的 PSRR）以及对低压差和低功耗有要求的消费电子产品。
五、布局与外部器件建议
为保证稳定性与瞬态响应，建议在输入端和输出端靠近器件放置去耦电容（推荐低 ESR 陶瓷电容），并尽量缩短走线；使能端应接入有明确逻辑电平的控制信号，若需抑制瞬态尖峰可在输入端加入适当的滤波。具体电容值与 ESR 要求请参照厂方数据手册确认。
六、封装与采购

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.
