HT7533线性稳压器(LDO)产品概述

HT7533是钜兴(JUXING) 推出的一款固定输出型线性稳压器(LDO),针对高输入电压转低电压、小电流稳压场景优化,具备低压差、低静态电流、多重保护等核心优势,广泛适配工业、车载、消费电子等领域的电源设计需求。

一、产品核心定位与基本属性

HT7533属于单通道正极输出LDO,核心定位为高输入电压(最大36V)→固定3.3V输出的小电流稳压器件,最大输出电流250mA,满足多数低功耗/小功率电路的供电需求。其设计聚焦“低功耗+高可靠性”,适合对静态电流敏感的电池供电系统,以及对电源纹波要求严格的精密电路。

二、关键电气性能参数解析

HT7533的性能参数精准匹配实际应用痛点,核心参数如下:

  1. 输入输出特性:
    最大输入工作电压36V(覆盖多数工业/车载电源的电压范围),输出固定3.3V(无需额外调整电阻,简化电路设计);最大输出电流250mA,可满足小型MCU、传感器等负载的供电;压差仅700mV@100mA(低压差特性),即使输入电压仅略高于输出(如4V),也能稳定输出3.3V,提升电源效率。
  2. 纹波抑制与静态电流:
    电源纹波抑制比(PSRR)达70dB@1kHz,能有效过滤输入电源的高频纹波(如开关电源的电磁干扰),保护后续敏感电路(如ADC、运放)的精度;静态电流仅2μA(典型值),远低于普通LDO的几十μA水平,适合电池供电设备(如智能手环、无线传感器)延长待机时间。

三、封装与应用场景匹配

HT7533采用SOT-89封装,体积小巧(尺寸约2.9×2.6×1.1mm),引脚为3针(输入IN、输出OUT、地GND),适配贴片自动化生产,适合空间紧凑的设备(如穿戴设备、小型控制板)。封装的散热性能满足小电流场景需求,无需额外散热片,进一步节省成本与空间。

四、保护功能与可靠性设计

为提升系统稳定性,HT7533内置三重保护机制:

  • 过流保护(OCP):当输出电流超过250mA阈值时,自动限制电流至安全范围,防止负载过流损坏;
  • 短路保护(SCP):输出端短路时,立即切断输出,避免芯片烧毁;短路故障排除后,自动恢复输出;
  • 过热保护(OTP):芯片结温超过150℃(典型值)时,关断输出;温度降至120℃左右时,自动重启,防止高温损坏。

五、工作温度范围与环境适应性

HT7533支持工业级温度范围(-40℃~+85℃@Ta),可在户外低温、车载高温等极端环境下稳定工作,无需额外温控电路。例如,在车载仪表盘、工业传感器节点中,能长期可靠运行,降低系统维护成本。

六、典型应用领域梳理

HT7533的性能与封装优势,使其适配以下场景:

  1. 低功耗手持/穿戴设备:智能手环、蓝牙耳机、计步器的3.3V辅助供电;
  2. 工业控制模块:传感器节点、小型PLC、电机驱动的控制电路供电;
  3. 车载电子:仪表盘背光、倒车雷达、胎压监测的稳压电路;
  4. 消费电子:小型家电(如加湿器、智能插座)的控制板供电;
  5. 通信设备:无线AP、路由器的低功耗模块(如WiFi模块)供电。

HT7533以“高输入电压+低静态电流+多重保护”为核心竞争力,为电源设计提供了低成本、高可靠的稳压方案,适合对体积、功耗、可靠性有要求的各类电子设备。

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
