产品概述：AMS1117-3.3 线性稳压器
一、产品简介
AMS1117-3.3 是一款以 JSMSEMI（杰盛微）品牌生产的线性稳压器（LDO），其主要特点为输出电压固定为3.3V，最大输出电流可达1A，采用SOT-223-3封装。该型号稳压器具有高达72dB的电源抑制比（PSRR）@120Hz，从而能够有效地抑制输入电源波动引起的输出电压波动。这使得AMS1117-3.3特别适合于对电源稳定性要求较高的应用场景，如消费电子设备、工业控制和通讯产品等。
二、功能特点
高输出电流能力：AMS1117-3.3能够提供高达1A的输出电流，使其能够满足大多数中小型电子设备的动力需求。其稳压效果良好，适用于需要较大电流的场合。
固定输出电压：该产品提供固定输出电压为3.3V，适合许多数字电路和微控制器等应用，减少了设计时对外部电压调节电路的需求，降低了设计的复杂性和成本。
优越的电源抑制比（PSRR）：其电源抑制比高达72dB@120Hz，意味着在输入电压波动或噪声较大的情况下，AMS1117-3.3仍能保持稳定的输出电压。这一特性在电源供应不稳定的环境中尤其重要，能够确保后端电路的正常工作。
低静态功耗：AMS1117-3.3设计考虑到低功耗特性，在不负载的情况下，其静态功耗非常小，可以有效提高整体系统的能效，延长电池供电产品的使用时间。
热保护和过流保护功能：该稳压器内部集成了热保护（Thermal Shutdown）和过流保护（Current Limiting）功能，能够在电流超过安全范围或温度过高时自动关断，保护电路的安全。
三、应用场景
AMS1117-3.3 适用的应用场合广泛，主要包括但不限于：
消费电子：如智能手机、平板电脑、便携式游戏机等。这些设备中元件的供电稳定性是确保正常工作的关键。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
