ETA5050V0S2F 产品概述

ETA(钰泰)ETA5050V0S2F 是一款面向空间受限、对噪声与电源稳定性要求高的低功耗线性稳压器。该器件为固定输出型、正极性单通道 LDO,输出电压为 1.0V,能够提供最高 500mA 的持续输出电流。产品集成短路保护、过流保护与过热关断等多重保护功能,并带有使能(EN)控制接口,适用于手持设备、便携式终端、传感前端与高精度模拟电源等应用场景。

一、主要特性概览

  • 品牌:ETA(钰泰)
  • 型号:ETA5050V0S2F
  • 输出类型:固定(1.0V)
  • 输出极性:正极
  • 输出通道数:1
  • 最大输出电流:500mA
  • 工作电压(输入):6V(器件额定工作电压)
  • 静态电流 (Iq):37 µA(低静态功耗,利于电池供电)
  • 噪声:50 µVrms(低输出噪声,适合敏感模拟电路)
  • 电源纹波抑制比(PSRR):73 dB @ 100 Hz(高抑制比,降低电源纹波对负载的影响)
  • 保护功能:短路保护(SCP)、过流保护(OCP)、过热保护(OTP)
  • 使能功能:带使能(EN)引脚,可实现软启/关断
  • 工作温度范围:-40℃ 至 +85℃
  • 封装:SOT23-5(小封装,利于空间受限的 PCB 布局)

二、电气特性亮点

  • 低静态电流(37 µA),在待机或低功耗模式下能够延长电池寿命;
  • 高 PSRR(73 dB @100Hz)对电池管理或开关电源输出作为上游电源时,能显著降低低频纹波传递到敏感模拟/射频前端;
  • 低输出噪声(50 µVrms)有利于高精度 ADC、放大器或参考电源的稳定性;
  • 支持高达 500mA 的输出驱动能力,能够驱动中等功率数码组件或放大级的偏置电流。

三、保护与可靠性设计

ETA5050V0S2F 集成了多重保护机制,提升系统可靠性:

  • 短路保护(SCP):在输出短路或严重过载时限制电流,防止器件损坏;
  • 过流保护(OCP):在超过设定电流阈值时进行电流限制,避免输出与上游电源发生异常;
  • 过热保护(OTP):当结温超过安全阈值时自动关断,冷却后自动恢复或可通过 EN 重启;
  • 这些保护配合低静态电流特性,能在多种工况下保证系统稳定与安全。

四、封装与引脚说明(SOT23-5)

  • 小型 SOT23-5 封装,适合便携与密集布局设计;
  • 器件带有使能(EN)引脚,便于外部逻辑控制电源开关和软启动;
  • 为获得最佳热性能与稳定性,建议在 PCB 上为 GND 引脚保留足够的散热面积并采用接地平面。

(注:具体引脚排列请参见厂商完整数据手册,以保证连接正确。)

五、典型应用场景与设计要点

适用场景:

  • 手持终端、电池供电设备的低压核心供电;
  • ADC、放大器、传感器前端的低噪声参考与偏置;
  • 无线通信模块、射频前端的模拟电源;
  • 工业与汽车电子的辅助电源(在器件工作温度与电压范围内)。

设计建议:

  • 输入与输出端使用低 ESR 陶瓷旁路电容(例如 X5R/X7R),以保证环路稳定及快速瞬态响应;典型情况下在输入端和输出端放置合适容量的去耦电容可显著改善性能;
  • 布局时尽量将输入、输出与 GND 走线短且粗,确保回路面积小,减小噪声耦合;
  • 对于高负载或大压差工况,注意器件功耗与散热,必要时在 PCB 采用热铜铺设或加装热沉。

六、产品优势总结

ETA5050V0S2F 将低噪声、高 PSRR 与低静态电流结合在小尺寸封装中,且提供全面的保护与使能控制,适合对空间、功耗以及电源质量有严格要求的应用。其 1.0V 固定输出与 500mA 的驱动能力,使其在多种便携与工业场景中成为可靠的线性稳压选择。

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
