RT9013-18GB 产品概述

一、产品简介

RT9013-18GB 是一款单通道、固定输出的低压差线性稳压器(LDO),由 TECH PUBLIC(台舟电子)提供。器件输出为正极性 1.8V,带使能(EN)功能,适合对噪声和电源纹波有较高要求的便携与低功耗应用。工作环境温度范围为 -40℃ 到 +85℃(Ta)。

二、主要规格

  • 输出类型:固定(1.8V)
  • 使能:带使能(EN 引脚)
  • 最大输出电流:500mA
  • 静态电流(Iq):60µA(典型,静态待机低耗)
  • 工作电压(Vin):7V(器件允许的工作电压上限)
  • 输出噪声:50µVrms
  • PSRR:70dB @ 1kHz
  • 输出通道数:1,正极性输出
  • 工作温度:-40℃ ~ +85℃(Ta)
  • 封装:SOT-23-5
  • 品牌:TECH PUBLIC(台舟电子)

三、性能亮点

  • 低静态电流(60µA)适合电池供电系统,待机功耗低,有利于延长待机时间。
  • 较高的输出电流能力(500mA)可驱动中等功率的数字负载、传感器和外围模块。
  • 出色的 PSRR(70dB @1kHz)与低噪声(50µVrms)保证对模拟前端、ADC、RF 接收等敏感电路的电源清洁度。
  • 带使能功能方便系统电源管理与电源顺序控制。

四、典型应用场景

  • 移动终端、便携式设备的核心电源与外设供电(MCU、传感器、存储器)。
  • 对噪声敏感的模拟前端、ADC 或无线射频前端。
  • 工业与消费类电子中需要稳定 1.8V 电源的模块。
  • 电池供电与节能型设计中的主/从电源管理。

五、封装与热管理

RT9013-18GB 提供 SOT-23-5 小封装,适合空间受限的 PCB 布局。设计时应关注热功耗:器件耗散功率约为 (Vin − 1.8V) × Iout,在满载或较大 Vin 情况下需通过加大 PCB 铜箔面积、设置散热过孔或降低输入电压来控制结温,确保在高环境温度下的可靠工作。

六、设计与使用建议

  • 输入和输出端推荐使用低 ESR 陶瓷电容作旁路,典型为 1µF~10µF,靠近器件引脚布局,保证稳定性与瞬态性能。
  • EN(使能)引脚高电平开启,低电平关闭,建议在上电顺序设计中明确 EN 的驱动来源,避免产生未定义状态。
  • 注意输入电压需高于输出电压加上器件的最低差分电压(dropout);如需在较低差压下工作,请参考器件详细数据手册确认电压裕量。
  • 布局时 GND 扎实、减少环路面积,以发挥 PSRR 和噪声抑制能力。

七、竞争优势与注意事项

RT9013-18GB 结合低静态电流、高 PSRR 与 500mA 输出能力,适用于对功耗与电源质量有双重要求的方案。相比于普通 LDO,其低噪声与优良的纹波抑制使其在模拟与射频前端有优势。注意在高 Vin 与高 Iout 条件下做好热设计,并严格按照厂商建议的外部电容规格与 PCB 布局规范实现最佳性能。若需特殊温度或更高电流版本,可与供应商联系以获取更多选型信息。

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
