BL8064CB3TR12 线性稳压器(LDO)产品概述

一 产品概述

BL8064CB3TR12 是贝岭(BELLING)推出的一款低压差、低静态电流的固定输出线性稳压器,采用 SOT-23-3 小封装,面向便携式与低功耗电子设备的 1.2V 电源稳压要求。该器件输出极性为正极,提供高达 200mA 的连续输出电流,具备使能控制与过流保护功能,适合为数字核心电压、模拟前端和传感器供电。

二 主要参数与特性

  • 输入电压上限(工作电压):6V(请按具体应用确保输入电压在器件允许范围内)
  • 固定输出电压:1.20V
  • 最大输出电流:200mA
  • 压差(Dropout):430mV @ 200mA(典型条件下)
  • 静态电流(IQ):约 5µA(待机/静态时低功耗)
  • 功能特性:使能(EN)控制、过流保护(OCP)
  • 工作环境温度:-40℃ ~ +85℃(Ta)
  • 输出类型:固定电压输出,单通道
  • 封装:SOT-23-3,小型化利于空间受限系统集成

三 性能亮点与适用性

  • 低静态电流使 BL8064CB3TR12 非常适合电池供电与待机功耗敏感的系统,如物联网节点、便携设备与可穿戴产品。
  • 430mV 的压差在满载(200mA)情况下仍能保持稳定输出,适用于输入电压明显高于 1.2V 的场景;但在高差压、高电流情况下会产生较大功耗与发热,需要热设计考虑。
  • 过流保护提高系统可靠性,避免负载短路或异常电流损坏器件或下游电路。
  • 使能功能方便实现电源域管理:可通过微控制器或控制信号在不需要时将稳压器置入关断状态,从而进一步降低系统平均功耗。

四 引脚与封装(概述)

BL8064CB3TR12 采用 SOT-23-3 小封装,典型三引脚功能包含:输入(IN)、地(GND)、输出(OUT/EN 或 OUT 与独立 EN)。器件带有使能控制,具体引脚排列与使能逻辑(高电平使能或低电平使能)请参考厂家数据手册与封装引脚图以获得准确信息。

五 典型应用场景

  • 数字核心电源:为 MCU/SoC 的 1.2V 内核供电
  • 低压模拟与传感器前端:稳定低噪声电源保障信号完整性
  • 电池供电设备:智能门锁、远程传感器节点、可穿戴设备
  • 便携式消费电子:耳机、手持终端、便携式测量仪器

六 设计注意事项与推荐

  • 热耗与散热:线性稳压器的功耗等于 (Vin - Vout) × Iout。在最坏情况(Vin 接近 6V,Vout=1.2V,Iout=200mA)时,器件耗散近 0.96W,SOT-23-3 封装需通过 PCB 铜箔散热、降载或降低输入电压来控制结温,避免热关断或长期高温应力。
  • 输入/输出去耦:建议在输入端和输出端靠近芯片焊盘放置所需的旁路电容以保证稳定性与瞬态响应。常用陶瓷电容范围为 1µF~10µF,具体电容值与 ESR 要求请参照器件数据手册以确保稳压器工作稳定。
  • 使能控制:使用 EN 引脚实现电源开关功能时,应确认使能逻辑电平和允许的控制电压范围。若 EN 为高电平使能,确保控制器在上电序列中不会误触发。
  • 过流保护与启动性能:过流保护提供保护但会影响在异常负载下的输出行为。设计时注意考虑软启动/负载突变对系统的影响。
  • PCB 布局:输入侧走线要短且宽,输出侧和地的回流路径要低阻,GND 应良好接地以降低噪声;尽量把热量通过铜箔扩散到更大区域,必要时增加散热面积或使用多层 PCB 的内层铜平面。

七 采购与封装信息

  • 型号:BL8064CB3TR12
  • 品牌:BELLING(贝岭)
  • 封装:SOT-23-3,适合大批量表面贴装生产
  • 订货与替换:在实际设计与采购前,建议获取并核对供应商的完整数据手册、封装与引脚图、以及实际样片以验证特性。批量应用时注意 ESD、防潮与回流焊工艺规范。

总结:BL8064CB3TR12 以其低静态电流、使能控制与过流保护等特性,适合对待机功耗敏感且需 1.2V 稳压的小型电子设备。设计时需重点考虑功耗发热与去耦/布局细节,以确保稳定可靠运行。有关引脚定义、典型应用电路与电容 ESR 要求等,请参考贝岭官方数据手册以获得完整规范。

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.
