HT7536S —— 3.6V 固定线性稳压器(LDO)产品概述

一、产品简介

HT7536S 是友台半导体(UMW)推出的一款高压差、低静态电流的固定输出 LDO 稳压器,输出电压为 3.6V,支持最高输入电压 30V,输出电流最高 100mA。器件集成了过流保护和短路保护,工作温度范围为 -40℃ ~ +85℃,采用 SOT-23 小型封装,适合空间受限且需良好稳压与保护功能的便携与工业应用。

二、主要特性

  • 固定输出:3.6V(正极输出)
  • 最大输入电压:30V
  • 最大输出电流:100mA
  • 压差(Dropout):典型 200mV(视温度与负载变化)
  • 静态电流 Iq:典型 3μA,适合低功耗应用
  • 内置保护:过流保护与短路保护,提高系统可靠性
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOT-23,3 引脚(常规引脚分配 VIN / GND / VOUT)

三、应用场景

  • 电池供电的便携设备与传感节点(IoT、可穿戴)
  • MCU、传感器和射频模块的 3.6V 电源轨
  • 工业控制、家电与仪器仪表中对过流/短路保护有要求的小功率稳压电源
  • 需要低静态电流以延长待机寿命的系统

四、设计建议与注意事项

  • 输出电容:为保证 LDO 稳定性与瞬态响应,建议在 VOUT 端使用 1μF~10μF 的低 ESR 陶瓷电容,电容和整流器布局请尽量靠近 VOUT 引脚布置。
  • 输入电容:靠近 VIN 引脚放置 0.1μF~1μF 陶瓷电容以抑制输入噪声与寄生。
  • 散热与电源差谨慎评估:线性稳压器的功耗 Pd = (Vin - Vout) × Iout。举例,在 Vin = 30V、Vout = 3.6V、Iout = 100mA 时,Pd = 2.64W,SOT-23 封装难以安全散热,可能导致过热与热关断。以常见 PCB 热阻 θJA ≈ 150–250℃/W 估算,建议在 100mA 工作条件下尽量使 Vin - Vout 不超过约 5V(即 Vin ≤ ~8.6V),或降低输出电流、改进 PCB 散热/换用散热能力更强的器件。
  • 保护特性:内部限流与短路保护可在故障时保护器件与负载,但长期靠限流工作会产生较高热量,仍建议避免持续短路状态。
  • 典型电路:VIN 接电源,靠近放置输入去耦电容;VOUT 接输出去耦电容并供给负载;GND 接地平面以优化热与电性能。

五、产品优势

  • 极低静态电流(3μA)适合低功耗系统与长待机应用
  • 支持高达 30V 的输入,便于直接由高压电源或整流后的电压取电(注意散热)
  • 小尺寸 SOT-23 封装便于紧凑设计与量产替换
  • 内置过流/短路保护提升系统鲁棒性

HT7536S 适用于需要稳健保护、低待机电流与小体积封装的中低功率供电场合。设计时请重点考虑输入与输出电压差带来的功耗与散热约束,以确保长期可靠运行。若有更具体的电路参数或典型曲线需求,可进一步查看器件数据手册或咨询厂商技术支持。

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
