ISL21010CFH330Z-TK 产品概述

一、产品简介

ISL21010CFH330Z-TK 是瑞萨(Renesas)推出的一款高精度、低噪声的固定输出串联电压基准芯片。器件在输入电压范围 3.1V 至 5.5V 下提供稳定的 3.000V 输出,最多可驱动 25mA 负载,适合对电压精度与噪声敏感的模拟与混合信号系统。封装采用常用的 SOT-23-3,体积小、便于 PCB 集成。

二、主要特性

  • 输出类型:固定(3.0V)
  • 输入电压范围:3.1V ~ 5.5V
  • 输出电流:最大 25mA
  • 初始精度:±0.2%
  • 温度系数:50 ppm/℃
  • 基准类型:串联(Series Reference)
  • 静态工作电流(Iq):典型 100 μA
  • 低频噪声(0.1Hz–10Hz):86 μV p-p
  • 宽带噪声(10Hz–10kHz):36 μV rms
  • 工作温度范围:-40℃ ~ +125℃(Ta)
  • 封装:SOT-23-3

三、电气性能与优势

该器件在初始精度与温漂方面表现优秀,±0.2% 的初始误差配合 50ppm/℃ 的温度系数,能保证在工业级温度范围内的长期稳定性。低静态电流(100 μA)适合电池供电系统,同时在需要较大驱动能力时可提供最高 25mA 的输出电流。噪声指标低,适合高精度 ADC 参考、电源监测及精密测量前端。

四、典型应用场景

  • 高分辨率 ADC、采样系统参考电压
  • 精密传感器前端与数据采集模块
  • 电源管理与电压监测电路
  • 工业控制、仪器仪表以及便携式仪表设备

五、封装与布局建议

SOT-23-3 封装便于小面积布板。在 PCB 布局上建议:

  • 将参考输出与相关精密器件(如 ADC)走线最短并避免与数字地相邻的噪声源平行走线;
  • 在输出端靠近基准芯片放置 0.1 μF 至 1 μF 的旁路电容以降低高频噪声;
  • 若系统对低频噪声极为敏感,可在输出增加适当的滤波(RC 或低噪声缓冲)但需注意输出驱动能力与稳定性。

六、选型与注意事项

  • 确认输入电压始终高于 3.1V,以保证稳定 3.0V 输出;
  • 输出驱动超过 25mA 时可能导致输出偏差或热失稳;
  • 在高温或大电流应用中注意功耗与散热。

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
