Product Details

TPS79301DBVRQ1 Product Information

🧩 一、型号完整确认与封装信息

项目内容
完整型号TPS79301DBVRQ1
品牌Texas Instruments (TI) — 德州仪器
型号分解TPS79301 = 基础型号(可调输出LDO)
DBV = 封装代码 → SOT-23-5(5引脚小外形晶体管封装)
R = 卷带包装(Tape & Reel)
Q1 = 汽车级认证(AEC-Q100)
封装形式SOT-23-5 (DBV Package),5引脚,体积极小,适合紧凑型设计
引脚定义① EN(使能)② GND(地)③ FB/NC(反馈/空脚)④ OUT(输出)⑤ IN(输入)

📊 二、核心技术参数

参数典型值 / 范围说明
输入电压范围2.7V ~ 5.5V适用于低压供电场景
输出电压范围1.2V ~ 5.5V(可调)通过外部电阻分压网络设置
输出电流200mA最大持续输出电流
压差(Dropout)典型 110mV @ 200mA极低压差,高效节能
电源纹波抑制比(PSRR)65dB @ 1kHz优秀的噪声抑制能力
输出噪声32µV RMS(典型)超低噪声,适合射频/模拟电路
静态电流(Iq)典型 170µA低静态功耗
关断电流1µA(典型)待机功耗极低
输出精度±1%(典型)高精度输出
工作温度范围-40°C ~ +125°C汽车级宽温范围
AEC-Q100认证✅ 通过符合车规标准

🔧 三、适用产品范围与典型应用

应用领域具体场景
🚗 汽车电子ADAS摄像头模块、车载传感器、车载信息娱乐系统、车身控制模块(BCM)、车载雷达供电
📱 便携设备蓝牙耳机、智能穿戴、手持仪器、便携医疗设备
📡 射频/无线模块WiFi/BT模块、GPS接收器、RF收发器供电(因其超低噪声特性)
🎛️ 模拟/混合信号电路精密运放供电、ADC/DAC参考电源、音频编解码器供电
🔋 电池供电设备需要低压差以延长电池寿命的场景

🌟 核心卖点:

低噪声 + 高PSRR + 低压差 + 车规级 → 这四个特性使其在汽车摄像头/雷达模块供电中非常受欢迎。

🔮 未来用量预测

  • 用量预测: 由于 汽车智能化(ADAS、域控、激光雷达) 持续增长,该芯片作为车规级LDO的需求在未来 12~18个月将持续温和增长

  • 供需判断: TI产的汽车级物料整体供应稳定,但若遇到TI产能调配,交期可能从8周延长至12~16周。

✅ 四、最终结论

维度结论
芯片定位TI车规级低噪声低压差可调LDO稳压器
最核心优势✅ 车规认证 + ✅ 超低噪声32µV + ✅ 低压差110mV
首选应用场景汽车ADAS摄像头/雷达模块供电、车载射频供电
价格评估近期 ¥3.2~¥4.0/pcs,属于车规LDO合理价位
库存状况全网库存中等(约40k~60k),暂不缺货,建议备货周期内下单
最佳替代方案非车规用 TPS79301DBVR(同封装同性能,价格更低)
风险提示若TI产能调整,车规Q1版本交期可能延长,建议提前4~6周锁定订单
