BL8568GCB5ATR15 — 线性低压差稳压器(LDO)产品概述

一、产品简介

BL8568GCB5ATR15 是贝岭(BELLING)推出的一款低压差线性稳压器,固定输出 1.5V、单通道输出,适用于对低噪声、电源稳定性和续航有较高要求的便携与嵌入式系统。器件采用紧凑的 SOT-23-5 封装,工作电压最高支持 6V,输出电流最高可达 500mA,适合为单片机、传感器、射频前端及模拟放大电路等供电。

二、主要参数与功能特性

  • 输出极性:正极(固定 1.5V 输出)
  • 工作电压:最高 6V
  • 输出电压:1.5V(固定)
  • 最大输出电流:500mA
  • 压差(Dropout):65mV @ 100mA(低压差,适合电池供电)
  • 电源纹波抑制比(PSRR):70dB @ 1kHz(优秀的纹波抑制能力)
  • 静态电流(Iq):80µA(低静态电流,有利于延长电池寿命)
  • 功能特性:使能控制(EN)、输出放电(Output Discharge)、过流保护(OCP)
  • 工作温度范围:-40℃ 至 +85℃(Ta)
  • 输出类型:固定输出,单通道
  • 封装:SOT-23-5

三、电气性能亮点

  • 低压差特性:65mV@100mA 的压差指示在轻载至中等负载下,可在极小的输入-输出电压差下仍维持稳定 1.5V 输出,适合锂电池或双节/单节电池减压场合。
  • 高 PSRR:在 1kHz 频率处达 70dB,有效抑制来自开关电源或外部干扰的纹波,适合敏感模拟、ADC 或 RF 前端电源供应。
  • 低静态电流:80µA 的静态电流有助于静态功耗控制,适合便携式及电池供电设备。
  • 保护机制:内置过流保护和输出放电功能,提升系统安全性与上电/关断时的确定性。

四、封装与典型引脚功能(SOT-23-5)

器件采用 SOT-23-5 小封装,利于空间受限的 PCB 布局。典型引脚功能包含:输入(VIN)、输出(VOUT)、地(GND)、使能(EN)、(有时为)放电或备用功能脚。具体的引脚排列和脚位电气参数请参见器件完整数据手册以获得精确信息。

五、典型应用场景

  • 便携式电池供电设备(如手持终端、便携式测试仪)
  • MCU、FPGA 或数字逻辑的低压电源轨
  • 模拟前端、ADC、音频放大电路与射频电路的低噪声电源
  • 工业控制与仪表中对可靠性与纹波抑制有要求的电源管理

六、使用建议与注意事项

  • 输出电容:为保证稳定性与瞬态响应,建议在输出端使用厂商推荐的低 ESR 电容(常见为陶瓷电容,值范围请参考数据手册)。
  • 输入电容:在 VIN 端放置合适的去耦电容以抑制输入噪声与充放电瞬态。
  • 热管理:SOT-23-5 封装的散热能力有限,器件功耗与结壳温升由 VIN−VOUT 与输出电流决定。在高电压差或大电流工况下,应注意 PCB 铜箔散热、加大热沉面积或降低功耗以避免过热。
  • 使能逻辑:EN 引脚用于外部开关控制,上电下电过程中的顺序与电压阈值请参考数据手册,输出放电功能可用于快速拉低输出以确保系统复位可靠。
  • 保护行为:过流保护在短路或过载时保护器件,但长时间短路应避免,以免造成过热。

七、结论

BL8568GCB5ATR15 凭借低压差、优异的 PSRR 与低静态电流,适合对电源噪声、效率与电池续航有较高要求的便携和工业应用。SOT-23-5 小封装利于紧凑设计,内置使能、输出放电与过流保护,为系统设计提供了方便与可靠性保障。欲获得完整电气规格、引脚定义及典型应用电路,请参阅贝岭官方数据手册以完成最终硬件设计与验证。

Sourcing availability signal

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
