L78L05ABUTR 产品概述

L78L05ABUTR 是意法半导体(STMicroelectronics)推出的一款线性稳压器,其主要功能是将输入电压稳定地输出为固定的5V直流电压。作为一种低压差(Low Dropout, LDO)稳压器,L78L05ABUTR 设计用于提供高效且可靠的电源管理解决方案,广泛应用于多种电子设备和电路中。

主要参数

L78L05ABUTR 具有以下关键参数:

  • 固定输出电压:该稳压器的输出电压为固定值5V,适合多个低电压电子项目。
  • 最大输入电压:它可以接受高达30V的输入电压,意味着它在面对电源波动或不同电源类型时拥有更大的适应性。
  • 输出电流:L78L05ABUTR 能够提供最多100mA的输出电流,适合驱动多种小型负载。
  • 功耗特性:其最大电压降(Dropout Voltage)为1.7V,这在以40mA负载运行时的典型值,确保在低负载情况下也能有效工作。
  • 静态电流(Iq):在静态条件下,设备的工作电流仅为5.5mA,确保在待机或轻负载情况下的高能效。
  • 过流、过温、短路保护:内置保护功能可防止设备因意外过载或过热而损坏,增强了系统的可靠性。

物理封装

L78L05ABUTR 采用SOT-89-3封装,其尺寸小巧,适合于表面贴装工艺。这种封装使得稳压器可以紧凑地集成到各种印刷电路板(PCB)设计中,节省空间并简化电路布局,非常适合现代电子产品的小型化需求。

性能优势

  1. 低纹波和高PSRR:L78L05ABUTR 在120Hz时的功率抑制比率(PSRR)为49dB,确保输出电压非常稳定,减少电源噪声的影响。这对于需要精密电源的数字电路和模拟系统至关重要。

  2. 广泛的工作温度范围:设备能够在-40°C到125°C的温度下稳定工作,使其适用于极端环境和工业应用。

  3. 易于使用:L78L05ABUTR 的设计使其易于集成到现有电路中,只需少量外部电容器即可实现平稳和安静的电源输出,大大简化了电源设计。

应用场景

L78L05ABUTR 适用于众多应用,包括但不限于:

  • 消费电子产品(如智能手机、平板电脑等)
  • 嵌入式系统
  • 家用电器和工业控制
  • 电源管理模块
  • 传感器供电

其稳定的性能和可靠的保护特性使其成为设计这些设备的理想选择。

总结

总体而言,L78L05ABUTR 是一款具有高性价比的固定输出线性稳压器,能够为各种应用提供稳定的电源,具有出色的电源管理能力和保护功能。凭借其小巧的SOT-89-3封装和广泛的输入电压范围,它在现代电子设备及其电源管理设计中发挥着极其重要的作用。无论是在工业应用、家庭电子产品,还是在便携式设备中,L78L05ABUTR 都能够满足设计者对高效、稳定和可靠电源的苛刻要求。

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
