LP5907MFX-3.3 产品概述
一、产品简介
LP5907MFX-3.3 是一款固定输出的低压差线性稳压器（LDO），由 TECH PUBLIC（台舟电子）提供，封装为 SOT-23-5。该器件针对低功耗与低噪声应用优化，输出电压为 3.3V，能够在宽输入电压范围内稳定工作，尤其适合电池供电和便携式电子设备的电源管理需求。
二、主要性能参数
- 输入电压范围：1.2V ~ 5.5V
- 输出电压：3.3V（固定）
- 最大输出电流：300mA
- 静态电流（Iq）：2µA（极低待机功耗）
- 压降（Dropout）：180mV @ 300mA
- 电源纹波抑制比（PSRR）：75dB @ 1kHz（良好的纹波抑制能力）
- 输出噪声：51µVrms（低噪声特性）
- 保护功能：过流保护、过热保护（热关断）
- 使能功能：带使能脚，便于系统电源控制
- 工作温度范围：-40°C ~ +150°C
- 输出极性：正极输出
三、产品优势
- 超低静态电流（2µA），适合电池供电、休眠占空比高的系统，延长系统待机时间。
- 低压降设计（180mV @ 300mA），在电源电压靠近目标电压时仍能维持稳定输出，适合单节锂电池等场景。
- 优秀的 PSRR（75dB @1kHz）与低输出噪声（51µVrms），对模拟前端、射频模块或高精度采集电路影响小。
- 完善的保护机制（过流、过热）提高系统可靠性，带使能引脚便于电源域管理与功耗控制。
- 宽温区性能（-40°C 至 +150°C），适应工业级和汽车级附近应用环境（需根据系统认证要求验证）。
四、典型应用场景
- 便携设备与可穿戴产品（延长电池寿命、低噪声供电）
- 物联网传感器节点、无线通信模块（稳定 3.3V 电源）
- 精密模拟电路、ADC/DAC 供电（低噪声、良好 PSRR）
- 工业控制与测量设备（宽温区、过热/过流保护）
五、设计和使用建议
- 输出与输入端建议靠近引脚放置低 ESR 陶瓷去耦电容（典型值 1µF ~ 10µF），以保证稳压器稳定性与瞬态响应。
- 使能脚用于系统电源管理，关闭时可将稳压器置于低功耗状态（静态电流显著降低）。
- 在高电流或高功耗场景下，注意器件散热与 PCB 散热设计，合理安排铜箔面积与热流路径以避免热关断。
- 在关键应用中建议进行实际电路下的纹波、噪声及热特性测试，验证在目标工作条件下的表现。
六、封装与可靠性
LP5907MFX-3.3 提供 SOT-23-5 小体积封装，便于空间受限的电路板设计。器件在-40°C 至 +150°C 范围内保证工作性能，适用于需要长期稳定性的工业与消费类产品。购买与生产应用中，请参考 TECH PUBLIC 官方数据手册与可靠性规范进行最终设计确认。

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.
