TLV70733PDQNR 线性稳压器(LDO)产品概述

TLV70733PDQNR是德州仪器(TI)推出的一款超小型、低功耗固定输出线性稳压器,专为电池供电的便携设备、工业传感器节点及高密度电子系统设计,在小尺寸、低噪声与宽温可靠性之间实现了均衡优化。

一、核心定位与设计目标

该器件聚焦三大核心需求:

  1. 极小封装适配高密度设计:采用1×1mm X2SON-4封装,满足智能穿戴、IoT模块等PCB空间极致紧张的场景;
  2. 低功耗延长电池寿命:以50μA静态电流(Iq)适配纽扣电池、锂电池等低容量供电场景;
  3. 宽温可靠性覆盖多领域:支持-40℃至+125℃结温范围,兼容工业、汽车电子等严苛环境。

二、关键性能参数解析

1. 输入输出基础规格

  • 输入电压范围:支持最高5.5V输入,兼容锂电池(3.7V典型值)、5V USB等常见电源;
  • 固定输出:精准3.3V输出,无需外部电阻调节,简化电路设计;
  • 输出电流能力:最大200mA,可驱动小型MCU、蓝牙模块、传感器等负载;
  • 低压差特性:150mA负载下压差仅250mV,即输入电压≥3.55V即可稳定输出3.3V,适配电池放电后期(电压下降至3.6V左右仍能正常工作)。

2. 噪声与纹波抑制

  • 低输出噪声:仅45μVrms(典型值),避免干扰敏感模拟电路(如ADC前端、传感器信号链);
  • 电源纹波抑制比(PSRR):100Hz下达70dB,有效抑制电源线上的低频纹波,提升输出纯净度。

3. 静态电流与效率

  • 超低静态电流:50μA(无负载时),若采用100mAh纽扣电池供电,仅静态电流即可支持设备待机超200年,极大延长电池寿命。

三、封装与引脚设计

TLV70733PDQNR采用X2SON-4-EP(增强型散热引脚) 封装,尺寸仅1×1mm×0.5mm(典型):

  • 4引脚布局:简化PCB布线,无需额外散热片即可通过EP引脚将热量传导至PCB;
  • 封装优势:比传统SOT-23封装体积缩小约70%,适合智能手表、蓝牙耳机、IoT传感器节点等小型化产品。

四、可靠性与保护特性

该器件内置双重保护机制,提升系统稳定性:

  1. 过流保护(OCP):输出电流超过阈值时自动限流(典型值250mA),防止负载短路损坏LDO及后端电路;
  2. 热关断(TSD):结温超过125℃时关闭输出,温度下降至恢复阈值后自动重启,避免高温下器件损坏。

五、典型应用场景

结合性能特点,TLV70733PDQNR广泛适配以下场景:

  1. 智能穿戴设备:智能手环、手表的传感器、蓝牙模块稳压,小封装节省空间,低Iq延长待机;
  2. 工业IoT节点:温度、压力传感器的电源管理,宽温范围兼容户外/工业环境;
  3. 便携电子:蓝牙耳机、智能音箱的辅助电源,低压差适配锂电池放电全周期;
  4. 汽车电子辅助模块:胎压监测、车身传感器的稳压,宽温及保护机制满足车载环境。

六、产品优势总结

  • 小尺寸与高集成:1×1mm封装集成稳压、保护功能,减少PCB占用;
  • 低功耗与长续航:50μA Iq实现电池供电设备超长期待机;
  • 低噪声与高纯净:45μVrms噪声适配敏感模拟电路;
  • 宽温与高可靠:-40℃~+125℃结温及双重保护,覆盖严苛应用场景。

TLV70733PDQNR凭借其均衡的性能与小尺寸优势,成为便携、工业及IoT领域稳压方案的高性价比选择。

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
