BL8064CC3TR50 产品概述

BL8064CC3TR50 是贝岭(BELLING)推出的一款高性能低压差线性稳压器(LDO),采用 SOT-89-3L 封装,提供单路固定 5V 输出,面向对功耗、体积和可靠性有较高要求的便携与嵌入式应用。器件具备低静态电流、使能控制与过流保护等实用特性,便于电源管理与系统保护设计。

一、主要特性

  • 输出极性:正极、固定输出 5.0V。
  • 输出电流:最大 200mA,适合中等负载供电。
  • 低压差性能:典型压差 600mV @ 100mA,有利于电池或低压轨供电场合。
  • 超低静态电流:Iq ≈ 1μA,适合低功耗待机系统。
  • 功能:外部使能(EN)控制、内部过流保护(OCP)。
  • 工作温度范围:-40℃ 至 +85℃(Ta)。
  • 封装:SOT-89-3L,便于中等功率散热与表面贴装工艺。

二、主要电气参数(概要)

  • 输入电压等级:工作电压 8V(器件典型/建议输入环境,请参见完整规格书以确认最高输入限值)。
  • 输出电压:5.0V(固定型)。
  • 最大输出电流:200mA。
  • 压降:600mV @ 100mA(示例条件),在更高电流时应关注压差和功耗。
  • 静态电流:≈1μA(典型,静态/待机时)。

注:具体精度、温漂、纹波抑制(PSRR)等参数请以原厂数据手册为准。

三、引脚与封装说明

  • 封装类型:SOT-89-3L,三引脚设计,便于与标准 PCB 工艺配合。
  • 常见引脚功能:输入(VIN)、输出(VOUT)、使能/地(EN/GND)等。具体引脚排列与引脚电气要求请参考器件引脚图和规格书。

四、典型应用与电路建议

  • 适用场景:传感器供电、MCU 低功耗子系统、便携设备辅助电源、工业控制模块等。
  • 去耦与稳定性:建议在输入端与输出端靠近引脚处分别放置低 ESR 陶瓷电容(常见 1μF~10μF),以保证稳压器在瞬态和负载变化时的稳定性与响应。
  • 使能控制:通过 EN 引脚实现外部软启或节能关闭,方便系统电源管理。使能电平与接法请参照手册。
  • 过流/短路:器件自带过流保护,但长期短路或高压差工况会导致器件发热,应配合热设计与限流电路使用。

五、热管理与布局注意事项

  • 功耗估算:稳压器功耗约为 (VIN − VOUT) × IOUT。在接近最大电流时,若 VIN 较高,器件功耗和结温显著升高,需要评估热裕量。
  • PCB 设计:建议在器件底部和地铜层处扩展散热铜箔,增加过孔连通多层铜层,有助降低结温并提升可靠性。SOT-89 在中等功率下散热性能优于小型封装,但仍需合理布局。
  • 环境条件:在高温或高负载工况下,应验证热关断与温度漂移对输出的影响。

六、使用注意事项与建议

  • 在选择输入电源时,应确保输入电压始终高于输出电压加压差裕量(例如 5V + 压降),以避免进入 dropout 状态。
  • 对于对输出精度、噪声或 PSRR 有严格要求的系统,建议查阅完整规格书中的典型曲线与测试条件,必要时在输出端增加滤波网络。
  • 推荐在产品开发初期通过实测验证稳压器在目标工况(温度、负载、输入波动)下的稳定性与热性能。

总结:BL8064CC3TR50 以其固定 5V 输出、低静态电流与实用的功能特性,适合需要低功耗待机与中等电流输出的各类电子设备。合理的输入选择、去耦电容与 PCB 散热设计可确保器件在实际应用中实现稳定、可靠的电源输出。

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
