HT7550 低压差线性稳压器产品概述

一、产品核心定位与应用场景

HT7550是GOODWORK(固得沃克) 推出的一款固定输出型低压差线性稳压器(LDO),专为低功耗、小负载电流、空间受限的电子系统设计。其核心是在宽输入电压范围内提供稳定的5V输出,同时兼顾极低静态功耗与宽温度适应性,典型应用覆盖:

  • 低功耗传感器节点(温湿度、压力、气体传感器供电);
  • 便携医疗设备(小型血糖仪、血氧仪辅助电路);
  • 无线低功耗模块(蓝牙5.0、ZigBee模块电源管理);
  • 工业控制小信号电路(PLC辅助传感器供电);
  • 纽扣电池/干电池供电的小型电子装置(如电子标签、智能门锁辅助电路)。

二、关键电气参数解析

HT7550的核心参数针对小电流、低功耗场景做了针对性优化,关键指标如下:

2.1 输入输出特性

  • 输出类型:固定正极输出,默认输出电压5V±1%(常规LDO固定输出精度);
  • 工作电压范围:最大输入电压30V(实际输入范围为5.025V~30V,因压差限制);
  • 输出电流能力:最大持续输出电流150mA,满足单个MCU、小型传感器组等小负载需求。

2.2 低压差优势

  • 压差性能:1mA负载电流下,压差仅25mV(输入电压只需比输出高25mV即可稳定工作);
  • 实际意义:电池放电后期(如5V锂电池降至5.025V)仍能输出稳定5V,延长续航周期。

2.3 极低静态功耗

  • 静态电流(Iq):仅1.5μA(典型值),远低于常规LDO的10μA以上水平;
  • 续航提升:以CR2032纽扣电池(容量≈220mAh)为例,无负载时静态功耗仅7.5μW,理论续航可达16年以上(带负载时仍保持数倍于同类产品的续航)。

三、封装与可靠性设计

HT7550采用SOT-23封装,具有以下设计优势:

  • 小尺寸:封装尺寸约2.9×1.6×1.1mm,节省PCB空间,适合高密度贴片布局;
  • 高可靠性:成熟贴片封装,抗振动、抗冲击能力强,适配工业/户外场景;
  • 易焊接:兼容常规回流焊工艺,自动化生产效率高,降低制造成本。

四、温度适应性与环境兼容性

HT7550工作温度范围为**-40℃+85℃(Ta),属于工业级温度范围**,相比消费级0℃70℃更具优势:

  • 低温场景:稳定工作于北方冬季户外(如-30℃环境下的传感器节点);
  • 高温场景:支持夏季车内(约60℃)、工业控制柜内(约70℃)等高温环境;
  • 热稳定性:自身最大功耗仅150mA×25mV=3.75mW,无需额外散热设计。

五、典型应用电路参考

HT7550应用电路极为简单,无需复杂外围元件,典型电路如下:

  1. 输入滤波:Vin与GND并联1μF陶瓷电容(抑制输入噪声,可选);
  2. 输出滤波:Vout与GND并联1μF陶瓷电容(稳定输出电压,抑制纹波);
  3. 负载连接:Vout直接接负载(如传感器、MCU),GND共地。

示例:为低功耗温湿度传感器(SHT30)供电时,仅需HT7550+2个1μF电容,即可实现30V输入到5V稳定输出,静态电流1.5μA,满足电池供电10年以上需求。

六、产品优势总结

HT7550相比同类LDO产品,核心优势集中在:

  • 超低静态电流:1.5μA,电池续航提升3~5倍;
  • 宽输入电压:支持5.025V~30V输入,适配电池、线性电源、开关电源;
  • 低压差:25mV@1mA,输入接近输出时仍稳定;
  • 工业级温度:-40℃~+85℃,覆盖广场景;
  • 小封装:SOT-23,适合空间受限设计。

综上,HT7550是低功耗、小电流电子系统的理想电源管理方案,尤其适合电池供电的便携/工业设备。

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
