GR6119C50M5G 产品概述

一、产品简介

GR6119C50M5G 是国睿(GR)推出的一款高精度、低噪音、低压差线性稳压器,采用先进 CMOS 工艺制造,支持最高 15V 的输入电压并输出稳定的 5.0V。器件内置精密参考电压、误差放大与相位补偿电路,驱动为低导通电阻 MOSFET 结构,能够在低压差条件下提供快速响应和高纹波抑制性能,适合对噪声与功耗有严格要求的便携与工业应用。

二、主要性能

  • 输入电压(V in):最高 15V
  • 输出电压(V out):固定 5.0V
  • 输出电流(I out):最大 300mA
  • 压差(Dropout):30mV(典型)
  • 静态电流(Iq):3µA(典型,适合电池供电)
  • 电源纹波抑制比(PSRR):40dB @ 1kHz
  • 工作温度范围:-40℃ ~ +85℃
  • 输出极性:正极(正向输出)
  • 输出通道:单通道,固定输出

三、关键特性

  • 使能控制(EN):外部使能引脚可实现输出开关,便于系统电源管理与省电设计。
  • 过流保护与短路保护:内置限流与短路保护电路,提高系统可靠性,防止输出异常时器件或负载损坏。
  • 低噪声与高 PSRR:专用误差校正与相位补偿设计,使得在1kHz附近达到 ≥40dB 的纹波抑制,适合对电源噪声敏感的模拟与射频前端。
  • 陶瓷电容兼容:器件稳定性经过优化,可直接配合体积小于钽电容的陶瓷电容使用,无需额外 0.1µF 的旁路电容,从而节省 PCB 面积与物料成本。
  • 封装小巧:SOT-23-5 小封装,便于空间受限的便携设备与高密度 PCB 布局。

四、典型应用场景

  • 5V 数字与模拟电源:单片机、传感器、接口电路等。
  • 电池供电与便携设备:凭借 3µA 的超低静态电流,适合待机时长要求高的应用。
  • 通信与射频前端:低噪声与良好 PSRR 有利于提升系统灵敏度与信号完整性。
  • 工业控制与仪表:宽输入电压和工业级温度范围(-40℃~+85℃)满足现场应用需求。

五、封装与选型注意事项

  • 封装:SOT-23-5,适合小体积设计。
  • 外围电容建议:为保证瞬态响应与稳定性,推荐在输入/输出侧配合小体积 X5R/X7R 陶瓷电容,常见选值范围为 1µF ~ 10µF(依据具体负载瞬态和布线情况调整)。由于内部已进行相位补偿,一般不再需要额外 0.1µF 旁路电容。
  • 热与散热:在接近 300mA 输出和较高差分电压时需注意功耗与封装温升,必要时通过 PCB 散热铜箔提高散热能力。
  • 系统集成:建议在设计阶段评估使能逻辑、电源开启顺序与保护动作阈值以满足系统级安全与可靠性需求。

总结:GR6119C50M5G 以其超低静态电流、极低压差、出色的噪声与纹波抑制,以及对陶瓷电容的良好兼容性,为便携、工业与通信类系统提供了一种体积小、性能优、成本低的 5V 线性稳压解决方案。

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
