BL1118CS8TR1833线性稳压器(LDO)产品概述

BL1118CS8TR1833是贝岭(BELLING) 推出的一款双路固定输出线性稳压器(LDO),专为需要稳定双路12V供电、且对保护功能有明确需求的电路设计,采用ESOP-8贴片封装,兼顾小体积与可靠性,适用于工业控制、通信设备等多类场景。

一、产品核心定位与基本属性

该器件属于固定输出型LDO,核心特点为双路独立正极输出,输出电压固定为12V,无需外部电阻调整;静态电流低至2mA,在负载变化时仍能保持稳定,适合对功耗敏感的应用;工作温度覆盖-20℃至+85℃,满足工业级环境的温度适应性要求。

二、关键电气参数与实际意义

BL1118CS8TR1833的电气参数经过优化,可直接匹配多数常规供电场景:

  1. 输出能力:单路最大输出电流1A,双路独立输出(总输出能力2A以内),可同时为两路12V负载供电,无需额外并联其他稳压器;
  2. 压差特性:1A负载下压差仅1.3V,即输入电压只需≥13.3V即可保证12V稳定输出,降低了对高压电源的依赖,提升系统电源设计灵活性;
  3. 静态电流:2mA的典型静态电流,远低于部分同规格LDO的5mA以上水平,尤其适合电池供电或长期待机的设备,减少待机功耗;
  4. 温度范围:-20℃~+85℃的工作温度,可应对户外环境(如车载、户外监测)的温度波动,无需额外散热升级即可稳定运行。

三、ESOP-8封装的优势与引脚特性

采用ESOP-8贴片封装,相比普通SOP-8封装,引脚间距更合理,散热面积略有提升,同时保持小体积(尺寸约4.9mm×3.9mm),适合高密度PCB设计:

  • 引脚功能包含:输入电压端(VIN)、双路输出端(VOUT1/VOUT2)、接地端(GND)、使能端(EN,部分型号可选,若未标注则为默认使能);
  • 封装兼容性:可直接匹配常规SMT贴装设备,生产效率高,适合批量应用。

四、核心保护机制与可靠性

为提升系统稳定性,BL1118CS8TR1833内置双重保护功能:

  1. 过流保护(OCP):当单路输出电流超过1A阈值时,自动进入限流模式,限制输出电流在安全范围(如1.2A左右),防止负载短路或过流导致的芯片损坏;
  2. 热关断(TSD):当芯片结温超过150℃左右的阈值时,自动关断输出,避免高温损坏;温度下降至安全范围(如120℃)后,自动恢复输出,无需手动重启。

五、典型应用场景

该器件的参数与功能匹配多类场景:

  1. 工业控制设备:如PLC模块、传感器节点,需要双路12V稳定供电,过流保护可防止传感器短路损坏;
  2. 通信终端:小型基站、路由器的辅助供电电路,低静态电流适合长期待机,双路输出可同时为射频模块与控制芯片供电;
  3. 车载电子:车载导航、行车记录仪的12V供电,-20℃~+85℃温度范围可应对车内温差;
  4. 消费电子:智能家居网关、智能音箱的内部供电,小体积封装适合紧凑结构设计。

六、应用设计注意事项

为保证性能稳定,设计时需注意:

  1. 输入电压要求:VIN需≥13.3V(1A负载时),若负载较轻,压差会进一步降低,输入电压可适当放宽;
  2. 滤波电容:输入/输出端建议并联10μF陶瓷电容(或电解电容),提升纹波抑制能力,降低输出电压波动;
  3. 散热设计:大负载(如单路1A持续运行)时,可在PCB上为GND引脚增加铜箔面积,增强散热;
  4. 负载匹配:双路输出需分别匹配≤1A的负载,避免单路过载导致保护触发。

BL1118CS8TR1833以其双路固定输出、低功耗、保护功能完善等特点,成为中低端稳压需求场景的实用选择,适合对成本与可靠性平衡有要求的电路设计。

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
