TJ7533AGF 产品概述

一、概述与主要特性

TJ7533AGF 是 HTC 提供的一款固定输出线性稳压器,输出电压为 3.3V,面向对低静态电流与简单电源管理有较高要求的便携与工业应用。器件集成了过流保护(OCP),工作电压范围宽,封装采用 SOT-89-3,便于在空间受限场合实现较好的散热与布局。

主要特性一览:

  • 输出电压:固定 3.3V(正极输出)
  • 最大输出电流:100 mA
  • 静态电流(Iq):约 1 μA(极低静态功耗,适合电池供电)
  • 压差(Dropout):600 mV @ 50 mA
  • PSRR:34 dB @ 100 Hz
  • 过流保护:内置,增强负载短路及异常保护
  • 工作电压上限:30 V
  • 工作结温度:-40 °C ~ +125 °C(Tj)
  • 封装:SOT-89-3,单通道

二、电气规格要点

  • 对于典型工作点,器件在 50 mA 负载时压差约 600 mV;在更高负载(接近 100 mA)时压差可能有所增加,设计时需考虑输入电压裕量。
  • 超低静态电流(1 μA)显著降低待机功耗,适宜长期待机或窄功耗预算的系统。
  • PSRR 在低频(100 Hz)下约 34 dB,可有效抑制电源线上的低频纹波,但对更高频噪声可能需额外滤波措施。

三、封装与热管理

SOT-89-3 封装体积小、热阻适中,适合中低功率散热要求的场合。虽然封装有一定散热能力,但在输出接近 100 mA 且输入电压较高时会产生显著功耗(P = (Vin - 3.3V) × Iout),应注意布局中的散热路径、铜箔面积及附近热源,必要时考虑外部散热或改用更大封装。

四、典型应用场景

  • 电池供电的便携设备、传感器节点与可穿戴设备(受益于低 Iq)
  • 工业控制与仪表(宽输入电压至 30 V)
  • 嵌入式单板电源的局部 3.3V 供电
  • 需要基本过流保护与简单电压稳压的消费类电子

五、设计与布局建议

  • 输入电压需要保证在 Vout + Vdrop 以上,举例:在 50 mA 时建议 Vin ≥ 3.9 V;若需在 100 mA 运行,应参考原厂数据表估算更高的压差裕量。
  • 输出与输入端建议各配置旁路电容,常用低 ESR 陶瓷电容(例如 1–10 μF)贴近管脚以保证稳定与瞬态响应;具体电容值与 ESR 要求请以 HTC 原厂资料为准。
  • PCB 布局上应尽量缩短输入/输出走线,增大与地的散热铜箔,确保过流事件时器件不会因热量积累而触发热关断或寿命劣化。
  • 虽有过流保护,设计时仍应避免长期短路或超额载流运行。

六、优势与注意事项

优势:

  • 极低静态电流适合低功耗/待机场合;单芯片解决 3.3V 供电需求;宽工作电压与内置过流保护提升系统可靠性。

注意事项:

  • PSRR 在 100 Hz 下为 34 dB,对高频开关噪声需配合滤波电路;
  • 压差随电流上升而增大,100 mA 输出时的压差与功耗需评估热耗;
  • 具体引脚定义、启动特性、温度保护行为以及电容稳定性等关键细节,请以 HTC 原厂数据手册为准。

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
