TLV709A50DBVR 产品概述

一、产品简介

TLV709A50DBVR 是德州仪器(TI)推出的一款固定输出 5.0V、额定输出电流 150mA 的低压差线性稳压器(LDO)。器件最大工作电压可达 30V,静态电流仅 3.2μA,适合对待机功耗要求严格的便携和低功耗系统。封装为 SOT-23-5,集成过热保护与过流保护,适用于空间受限的工业与消费类应用。

二、主要性能指标

  • 输出类型:固定 5.0V 正极输出,单通道
  • 最大输入电压:30V(应保证器件额定范围内工作)
  • 最大输出电流:150mA,压差(Dropout):约 1V @ 150mA
  • 静态电流(Iq):3.2μA,利于延长电池寿命
  • 噪声:487μVrms,电源纹波抑制比(PSRR):60dB @ 100kHz
  • 保护特性:过热保护、过流保护
  • 工作温度范围:-40℃ 至 +125℃(结温标注)
    以上为典型/用户提供参数,最终设计请以 TI 官方数据手册为准。

三、典型应用场景

  • 电池供电设备与便携终端:低静态电流适合睡眠/待机模式,5V 输出可为 MCU 外设或传感器供电;
  • 工业控制与传感器节点:宽输入电压上限(30V)方便直接从较高母线降压(但需注意功耗);
  • 测试与测量设备、小型外围电源:良好 PSRR 与中等噪声性能适合多数模拟前端。

四、热设计与布局建议

线性稳压器的功耗由 (Vin - Vout) × Iout 决定。若在极端情况下 Vin = 30V、Vout = 5V 且 Iout = 150mA,则器件耗散功率约为 3.75W,远超 SOT-23 封装散热能力,必然触发热保护并导致输出降额。因此建议:

  • 在高输入电压或高负载场合改用开关降压或在输入端加前级限压;
  • PCB 上给稳压器留足铜箔散热面,增大接地平面并使用热过孔;
  • 输入/输出电容按 TI 手册推荐配置并靠近器件引脚布局,以保证稳定与瞬态响应。

五、选用建议与注意事项

  • 若系统常态工作在 Vin - Vout 较大且需持续 100mA 以上负载,优先考虑开关稳压以降低整体功耗与发热;
  • 对噪声与 PSRR 有更高要求的模拟前端,需评估 487μVrms 噪声与 60dB@100kHz 的抑制是否满足目标;
  • 在最终设计前务必参照 TI 官方数据手册确认推荐的输入/输出电容类型与值、封装热阻及典型性能曲线。

总结:TLV709A50DBVR 以其超低静态电流、单芯片保护与紧凑 SOT-23-5 封装,适合多数对功耗敏感且输入电压可控的应用场景;但在高压差高电流工况下需重视热管理或考虑替代方案。

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
