LP2985AIM5-5.0/TR 产品概述

一、概述

LP2985AIM5-5.0/TR 是华冠(HGSEMI)推出的一款高性能、低压差(LDO)线性稳压器,固定输出 5.0V,正极输出。器件支持使能控制与噪声旁路功能,额定工作电压最高可达 16V,输出电流可达 150mA,适合对噪声和稳定性有较高要求的小型便携与板载电源设计。

二、主要规格

  • 输出电压:5.0V(固定)
  • 输出电流:150mA(典型可用负载能力)
  • 工作电压:最高 16V
  • 压差(Dropout):165mV @ 150mA
  • 静态电流(Iq):600μA
  • PSRR:75dB @ 100Hz
  • 工作温度:-40℃ ~ +85℃
  • 输出极性:正极
  • 输出通道数:1 路
  • 封装:SOT-23-5

三、功能特性

  • 使能控制(EN):外部逻辑可快速打开或关闭输出,便于系统电源管理与省电设计。
  • 噪声旁路端子(BP/NR):外接旁路电容可进一步降低输出噪声与提高瞬态响应。
  • 反极性电压保护:内置防反接机制,提高系统可靠性与现场容错能力。
  • 过流保护 & 热关断:内建限流与过热保护,防止输出短路或过载时器件损坏。
  • 低静态电流与高 PSRR:适用于供电噪声敏感的模拟/混合信号模块,如射频前端、ADC、音频电路等。

四、优势分析

  • 低压差(仅 165mV@150mA)允许在较低输入-输出压差下工作,有助于延长电池供电时间或简化电源级设计。
  • 在 100Hz 处 75dB 的高 PSRR 能显著抑制整流与开关噪声,提升模拟和音频子系统性能。
  • SOT-23-5 小封装适合空间受限应用,同时外部元件少,易于布局与量产。

五、应用建议与注意事项

  • 输出端建议使用适当的低 ESR 电容(常见为 1μF 陶瓷)以确保稳压器稳定并优化瞬态响应;参考实际器件数据手册中推荐的电容值与 ESR 范围。
  • 若要求更低输出噪声或更好瞬态性能,可在噪声旁路端子接 0.01–0.1μF 旁路电容。
  • 使用使能功能时,应保证使能输入电平符合器件门限规格,并避免在 EN 引脚悬空。
  • 封装热阻有限,长时间高负载运行需关注热管理与 PCB 散热,建议合理铺铜并留意环境温度以避免触发热关断。
  • 虽然具备反极性保护,但在电源设计阶段仍建议采取必要的输入保护器件以满足更严格的系统安全需求。

LP2985AIM5-5.0/TR 结合低压差、高 PSRR 与多重保护功能,是便携设备、传感器节点、音频前端与精密模拟电源等多种场景的理想选择。如需器件封装图、引脚定义及详细电气参数,请参考华冠(HGSEMI)官方数据手册。

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
