产品概述：RT9166-12GVL

概述
RT9166-12GVL是一款由台湾立锜（RICHTEK）制造的线性稳压器（LDO），专为需要高稳压精度和低输出纹波的应用场合设计。该器件具有固定输出电压1.2V，最大输入电压为5.5V，并提供高达300mA的输出电流，适用于各种便携式电子设备、电源管理系统以及其他要求稳定电源供给的场景。

性能特点

  1. 电源与输出参数

    • 输入电压范围：该LDO的最大输入电压为5.5V，使其能够兼容多种供电方案，适应各种设计需求，尤其是在电池驱动的应用中。
    • 固定输出电压：RT9166-12GVL的输出电压固定为1.2V，非常适合一些特定的数字电路和微控制器的供电需求。
    • 输出电流：器件支持高达300mA的输出电流，能够满足大多数低功耗电路的供电要求。

  2. 低压降特性

    • 最大压降：此LDO在300mA的负载下，最大输出压降为230mV（典型值），表明其在负载变化时具有良好的电源效率。低压降特性有助于在电池电量降低时依然保证稳定的输出电压。

  3. 良好的电源抑制比

    • PSRR：RT9166-12GVL的电源抑制比（PSRR）为55dB（1kHz），这意味着在输出电压上的交流干扰信号能够被有效抑制，确保最终输出电压的稳定性，减少了负载敏感电路中的噪声问题。

  4. 温度与功耗

    • 工作温度范围：该稳压器的工作温度范围广泛，从-40°C到85°C，适应制冷和加热等恶劣环境。相对稳定的工作特性使其在工业和消费类电子产品中都能得到应用。
    • 静态电流（Iq）：在静态状态下，该器件的静态电流为300µA，这使得它非常适合需要低待机功耗的应用，进一步提高了能效。

  5. 保护功能

    • 该器件内置过流保护和过温保护功能，提升了其可靠性和稳定性，保护设备免受意外情况的损害。

封装与安装
RT9166-12GVL采用SOT-23-3L封装，具有出色的体积小巧性，非常适合表面贴装（SMD）技术使用。这种封装方式不仅节省了 PCB 占用面积，还简化了焊接工艺，提高了生产效率。

应用领域
RT9166-12GVL广泛应用于：

  • 便携式电子设备：如智能手机、平板电脑等，以提供稳定的电源供给。
  • 微控制器及数字信号处理器供电：能满足数字电路对电源的特定需求。
  • 工业设备及传感器供电：在恶劣环境中保持稳定性能。
  • 电池管理系统：在多种电池模式下维持设备的高效运行。

总结
RT9166-12GVL凭借其优良的电源参数、低压降特点及极低的静态电流，非常适合低功耗及高稳定性需求的终端应用。无论是在消费电子、工业控制还是通信设备的设计中，它都能作为一个可靠的稳压解决方案，帮助设计师应对日益严格的供电要求。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
