产品概述:L78L05ABD13TR

简介

L78L05ABD13TR 是由意法半导体(STMicroelectronics)生产的一款高性能线性稳压器(LDO),提供固定的 5V 输出电压,适用于各种电子应用。这款稳压器主要用于需要稳定电源电压的场合,如消费电子、工业设备、通信设备等,其特点是高可靠性、低功耗以及广泛的工作温度范围。

主要特点

  • 输出类型: 固定输出电压,即 5V,简化了电路设计并提供更高的可靠性。
  • 输入电压范围: 最大输入电压可达 30V,使其适用于多种电源配置,具有良好的灵活性。
  • 输出电流: 该器件能够提供高达 100mA 的输出电流,适合一般小功率负载的供电需求。
  • 静态工作电流(Iq): 该稳压器在静态工作状态下的电流仅为 5.5mA,表现出较低的功耗,非常适合电池供电应用。
  • 压降(Dropout Voltage): 在 40mA 输出电流下,最大压降为 1.7V,这意味着在输入电压与输出电压之间可以容许一定的压差,为设计提供了灵活性。
  • 功率抑制比(PSRR): 具有 49dB 的 PSRR 指标(在 120Hz 时测试),能有效抑制输入电源的纹波和噪音,从而保证输出电压的稳定性。

保护功能

L78L05ABD13TR 设计了多种保护功能以增强设备的可靠性和安全性:

  • 过流保护: 对于超过额定输出电流的负载,会自动限制输出电流,防止对电路的损害。
  • 超温保护: 内置的温度检测功能可防止器件因过热而损坏,当温度超过一定阈值时,LDO 会暂停工作以恢复正常温度。
  • 短路保护: 当输出端短路时,该器件能够及时识别并切断输出,保护后端电路的安全。

安装与封装

L78L05ABD13TR 采用表面贴装型(SMD)设计,封装为 8-SOIC(0.154",3.90mm 宽),使得其在现代紧凑电路设计中有良好的适应性。这种封装类型不仅提高了组装工艺的效率,还优化了产品的散热性能。

工作温度范围

该稳压器的工作温度范围为 -40°C 至 125°C,具备广泛的环境适应性,适合在多种工业和消费场景中使用,确保了设备在不同工作条件下的可靠性。

应用场景

L78L05ABD13TR 由于其稳定的输出特性和保护功能,广泛应用于:

  • 消费电子产品: 如音频设备、家用电器及移动设备等。
  • 工业控制设备: 用于各类传感器、电机驱动及控制电路。
  • 通信设备: 提供稳定的电源给网络设备及信号处理器。
  • 汽车电子: 在汽车电子系统中,提供可靠的电源管理解决方案。

结论

L78L05ABD13TR 是一款性能稳定、功能齐全的线性稳压器,凭借其高输入电压兼容性、卓越的输出稳定性和多种内建保护功能,能够满足各种设计需求。无论是在商用还是工业应用中,其可靠性与有效性都能够确保系统的稳定运行,是设计师们的理想选择。Choosing L78L05ABD13TR means choosing quality and reliability in power supply design.

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
