TPS7A0533PYKAR 线性稳压器(LDO)产品概述

TPS7A0533PYKAR是德州仪器(TI)推出的固定输出型低压差线性稳压器(LDO),属于TPS7A05系列的核心型号之一,主打超小封装、低静态电流与宽温适应性,专为空间受限、低功耗且对稳定性要求较高的应用场景设计。

一、产品核心定位与基本属性

该器件为单通道固定输出LDO,输出电压锁定为3.3V,输入工作电压范围适配常规电源(最高5.5V),封装采用DSBGA-4(超小型球栅阵列),尺寸紧凑(典型0.8mm×0.8mm),可显著节省PCB空间,适合便携式设备、物联网终端等高密度布局场景。

二、关键电气性能参数

TPS7A0533PYKAR的电气性能针对低功耗与稳定性优化,核心参数如下:

  • 输入输出特性:输入工作电压最高5.5V,固定输出3.3V;输出电流最大200mA,满足中小功率负载需求;压差典型值235mV(输出电流200mA时),确保轻载(如1mA)到满载的稳压精度(输出精度±2%典型值);
  • 功耗控制:静态电流(Iq)仅1μA(典型值),远低于常规LDO的几十μA,可有效降低系统待机功耗,延长电池续航时间;
  • 噪声与纹波抑制:输出噪声180μVrms(10Hz~100kHz带宽),适合对噪声敏感的模拟电路(如传感器前端、射频模块);1kHz时电源纹波抑制比(PSRR)达40dB,可有效抑制输入电源的纹波干扰,提升输出电源质量;
  • 输出精度:常温下输出电压精度±2%,宽温范围内(-40℃~125℃)保持±3%以内,满足大多数系统的供电精度要求。

三、集成保护与控制特性

为提升系统可靠性,该器件内置多重保护与控制功能:

  • 使能控制:支持外部使能引脚,可通过数字信号(如MCU GPIO)控制LDO的开启/关闭,便于系统功耗管理(如休眠模式下关闭LDO,进一步降低总功耗);
  • 过流保护(OCP):内置限流电路,当输出电流超过阈值(典型250mA)时自动限制电流,防止负载短路或过载损坏器件及后端电路;
  • 欠压锁定(UVLO):输入电压低于启动阈值(典型2.2V)时,LDO自动关闭,避免输出电压不稳定导致的系统异常;输入电压回升至阈值以上后自动重启;
  • 过热保护(OTP):结温超过150℃(典型值)时,LDO自动关断,防止器件因过热烧毁;结温回落至安全范围后恢复工作,保障长期可靠性。

四、封装与工作环境适应性

  • 封装:DSBGA-4封装,无引脚设计,散热性能良好,且可实现高密度贴装,适合小型化产品;
  • 工作温度:结温范围-40℃至+125℃,覆盖工业级宽温需求,可用于户外监测、车载电子、工业控制等恶劣环境;
  • 输出极性:正极输出,符合常规系统的供电极性要求,无需额外转换电路。

五、典型应用场景

TPS7A0533PYKAR的特性使其适配多种低功耗、空间受限场景:

  1. 便携式电子设备:智能手机、智能手环、蓝牙耳机等,利用小封装节省空间,低Iq延长电池续航;
  2. 物联网(IoT)终端:低功耗无线模块(如LoRa、蓝牙5.0)、智能电表、环境传感器节点,宽温范围适配户外部署;
  3. 工业控制模块:PLC辅助供电、远程监测传感器、工业物联网网关,多重保护提升系统可靠性;
  4. 模拟电路供电:传感器前端(如压力、温度传感器)、运算放大器、射频收发器,低噪声特性避免干扰;
  5. 电池供电系统:可穿戴设备、应急照明、便携式医疗设备,低静态电流显著提升电池使用时间。

综上,TPS7A0533PYKAR以超小封装、低功耗、宽温适应性与多重保护为核心优势,是工业级、便携式及物联网应用中3.3V固定输出供电的理想选择。

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
