H7211-12M5R 产品概述

一、产品简介

H7211-12M5R 是上海矽朋(Siproin)推出的一款低压差线性稳压器(LDO),为固定输出型 1.2V 正极单通道稳压器,封装为 SOT-23-5。器件带使能(EN)引脚和短路保护,适用于对噪声、纹波抑制和低静态电流有较高要求的便携与工业类电源应用。

二、主要性能参数

  • 输出电压:1.2V(固定)
  • 输入工作电压上限:6V(常规工作条件)
  • 最大输出电流:300mA
  • 静态电流(Iq):30μA(典型)
  • 压差(Dropout):380mV @ 150mA(在更高负载下压差会有所增加)
  • 纹波抑制比(PSRR):75dB @ 1kHz
  • 输出噪声:50μVrms
  • 保护特性:短路保护
  • 工作温度范围(Ta):0℃~+85℃
  • 封装:SOT-23-5(小封装,适合空间受限应用)

三、产品特点与优势

  • 低静态电流(30μA),适合电池供电或待机功耗受限的系统。
  • 优秀的 PSRR(75dB @ 1kHz)和低输出噪声(50μVrms),利于模拟前端、ADC/DAC 和射频敏感电路的供电。
  • 带使能控制,便于系统电源管理与节能;不使用时可通过 EN 引脚关断输出。
  • 内置短路保护,提高系统可靠性,防止异常负载损坏器件与系统。
  • SOT-23-5 小封装,便于表贴组装与批量生产。

四、典型应用场景

  • MCU/FPGA/ASIC 的核心电压 1.2V 供电(需核对允许电流与热耗)。
  • 便携式仪器、智能终端、传感器节点的低压供电。
  • 模拟电路、参考电源、低噪声电源轨。
  • 工业控制与消费类电子对噪声和纹波抑制有要求的场合。

五、布局与使用建议

  • 输入端应放置靠近 VIN 的去耦电容,推荐 1μF~10μF 陶瓷电容(X5R/X7R)以降低源阻和高频噪声。
  • 输出端需配合厂家建议的输出电容以保证稳态与瞬态响应,常见选择 2.2μF~10μF 陶瓷电容,注意电容 ESR 与芯片稳定性关系。
  • 若 EN 引脚不使用,建议拉高至 VIN(或按照数据手册规定的使能电平)以保证输出正常;使能端拉低可关闭输出、降低功耗。
  • SOT-23-5 封装热阻较大,高功耗或接近最大电流工作时应在 PCB 上增加铜箔散热区域以改善热性能,避免温升导致输出降额或热关断。

六、注意事项

  • 压差规格以标注条件为准(380mV @150mA),在 300mA 满载时压差和功耗会更高,需评估输入电压裕量与散热。
  • 工作环境温度受限于 Ta = 0℃~+85℃,极端环境或需更宽温区产品时请确认替代型号或与厂商沟通。
  • 在关键应用中,请参考完整数据手册获取精确的引脚定义、使能电平、启动/下降时间、保护阈值及外部电容稳定性要求。

七、采购与支持

H7211-12M5R 由 Siproin(上海矽朋)提供,封装为 SOT-23-5,适用于对低噪声、低静态电流与中等输出电流要求的系统。选型时建议下载并参照官方数据手册,或联系供应商获取样片、电路参考设计与布局建议,以保证产品在目标应用中的可靠性与性能表现。

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
