AH1117CLTR50 线性稳压器(LDO)产品概述

一、产品核心定位与品牌背景

AH1117CLTR50是贝岭(BELLING) 推出的一款固定输出型线性稳压器(LDO),属于AH1117系列的5V输出子型号。该产品主打高性价比、稳定可靠的中小功率直流电压转换场景,延续了贝岭在电源管理芯片领域的成熟设计,兼顾性能与成本控制,适合批量应用于消费电子、工业控制等领域。

二、关键电气参数解析

1. 电压与电流规格

  • 输出:固定5V直流电压,最大输出电流1A(满足多数中小功率负载,如单片机、传感器、小型显示模块);
  • 输入:典型工作电压12V,实际应用需确保输入电压≥输出电压+压差(1.5V@1A),即输入电压至少6.5V(5V+1.5V),最高输入电压建议不超过15V(避免超出器件耐受范围)。

2. 压差与静态电流

  • 压差:1.5V(1A负载下),相比部分高压差LDO更灵活,适配低压差场景(如12V转5V);
  • 静态电流:3.5mA,待机/轻载时功耗可控,不会过度消耗系统电源。

3. 环境与极性

  • 工作温度:-20℃~+85℃(环境温度Ta),覆盖普通工业与消费电子的典型环境;
  • 输出极性:正极,引脚配置符合通用定义,便于电路设计与替换。

三、封装与引脚配置

采用SOT-223-3封装(小型化表面贴装),尺寸紧凑(约6.5×3.5×1.6mm),适合空间受限的PCB设计。引脚定义(固定输出无调整端):

  • 引脚1:输入(IN)→ 接直流输入电压;
  • 引脚2:输出(OUT)→ 接负载与输出滤波电容;
  • 引脚3:地(GND)→ 接系统地。

四、主要功能特性

1. 固定输出精度

输出电压为固定5V,精度满足常规需求(通常±1%),无需额外调整电路,简化系统设计。

2. 热关断保护

内置热关断功能,当器件结温超过阈值(约150℃)时自动关断输出,防止过载、短路或高温导致的器件损坏,提升系统可靠性。

3. 低纹波输出

线性稳压器本身低纹波特性,结合外部滤波电容(输入/输出各并联10μF陶瓷电容),可将纹波降至mV级,适配对电源噪声敏感的负载(如模拟传感器、音频电路)。

五、典型应用场景

  1. 消费电子:便携式设备(移动电源、蓝牙音箱)辅助电源、小型家电(加湿器、智能台灯)控制电路供电;
  2. 工业控制:传感器节点、PLC模块的12V转5V转换、小型电机驱动控制电源;
  3. 通信设备:路由器/交换机内部辅助电源、WiFi/Bluetooth模块供电;
  4. 车载常温场景:行车记录仪、车载充电器辅助电源(-20~85℃覆盖部分车载环境)。

六、使用注意事项

  1. 输入电压限制:需确保输入电压≥6.5V(5V+1.5V),避免输出跌落;
  2. 滤波电容:输入/输出端并联≥10μF陶瓷电容(ESR≤1Ω),提升稳定性;
  3. 负载电流:避免长时间过载(持续电流超1A),防止热关断;
  4. 散热设计:负载电流接近1A且环境温度≥85℃时,需在PCB增加散热铜箔;
  5. 静电防护:生产过程需防静电操作,避免器件损坏。

该产品凭借稳定的性能、紧凑的封装与合理的成本,成为中小功率5V电源转换的常用选择,适配多领域应用需求。

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
