ETA5050V12S2F 产品概述
一、产品简介
ETA5050V12S2F 是钰泰（ETA）推出的一款低功耗、低噪声的固定输出线性稳压器，封装为 SOT-23-5，额定工作电压为 6V，固定输出电压 1.2V，输出通道为单路，输出极性为正极。器件面向对电源噪声和纹波抑制要求较高的便携类与精密电子应用，兼顾节能与保护功能。
二、主要性能特点
- 输出电压：1.2V（固定）
- 最大输出电流：500mA
- 工作电压（额定）：6V
- 电源纹波抑制比（PSRR）：70dB（典型）
- 静态电流（Iq）：37µA（低静态功耗，利于电池供电）
- 输出噪声：50µVrms（低噪声）
- 保护功能：过流保护（OCP）、过热保护（Thermal Shutdown）
- 控制功能：带使能（EN）引脚，可用于软启或关断功耗控制
- 工作结温范围：-40℃ ～ +125℃（Tj）
三、优势解析
- 高 PSRR 与低噪声：70dB 的纹波抑制配合 50µVrms 的噪声性能，使本器件非常适合对电源纯净度要求高的模拟前端、ADC/DAC、RF 前端等场景，能有效抑制输入电源干扰对系统性能的影响。
- 低静态电流：37µA 的静态电流降低待机功耗，有利于电池供电的便携设备和物联网终端延长电池寿命。
- 保护与控制：内置过流与过温保护保证工作可靠性，带使能端便于系统电源管理和电源序列控制。
- 小体积封装：SOT-23-5 封装适合空间受限的 PCB 布局，便于消费类与工业类产品的模块化设计。
四、典型应用
- MCU/FPGA/ASIC 的核心电源（1.2V 核心轨）
- 高精度模拟电路、ADC/DAC 供电
- 无线通信模块、射频前端的低噪电源
- 便携式仪器、传感器节点、电池供电设备
五、封装与实装注意事项
ETA5050V12S2F 采用 SOT-23-5 小封装，PCB 布局时应注意散热与去耦：
- 输入与输出侧建议并联低 ESR 陶瓷去耦电容以保证稳定性与瞬态响应，典型值可在 1µF–10µF 范围内选择（具体参考器件 Datasheet）。
- 将 GND 引脚短而粗地连接到地平面，以利于热量传导与降低阻抗。大功率工作场景下，考虑增大铜箔面积以改善散热。
- EN 引脚用于外部控制，设计时需考虑上拉/下拉电平以匹配系统逻辑。
六、选型与验证建议
在最终选型前建议确认以下参数：输入电压余量（确保在各工况下输入电压高于 1.2V + 丢失裕量）、瞬态响应与负载突变时的稳定性、器件在实际 PCB 板上散热能力以及 PSRR 在目标频段的表现。设计初期可通过评估板或参考电路进行实测，重点关注输出纹波、瞬态恢复和温升特性，以确保在目标应用中稳定可靠。

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.
