NJM78L08UA-TE1 — 固定输出线性稳压器（8V / 100mA，SOT-89）
一、产品概述
NJM78L08UA-TE1 是 NISSHINBO 推出的固定输出线性稳压器，额定输出 8V（典型范围 7.6V~8.4V），最大输出电流 100mA。器件面向需要简单、可靠、抗干扰能力强的低功耗电源前端或轨稳压场合，采用 SOT-89 小外形封装，适合空间受限的电路板布局与中等功率散热要求场景。
二、主要特性
- 固定输出：8V（输出公差约 ±5%，规格给出 7.6V~8.4V）
- 最大输入电压：30V（器件允许的工作电压）
- 最大输出电流：100mA
- 静态电流（Iq）：2.1mA（静态消耗，适用于常开供电场合）
- 电源纹波抑制比（PSRR）：66dB @ 120Hz（良好的低频纹波抑制能力）
- 噪声：115μV（典型）
- 保护功能：过流保护（OCP）、过热保护（OTP）
- 工作温度：-40℃ ~ +85℃（Ta）
- 输出极性：正极，单路输出
- 封装：SOT-89
三、电气性能要点
该器件在 120Hz 下提供约 66dB 的 PSRR，适合削弱来自整流/开关源的低频纹波；典型噪声 115μV，能够满足对噪声敏感的模拟或混合信号链的中等需求。静态电流 2.1mA 表明在待机或持续上电时有固定功耗，应在系统能量预算中考虑。
四、保护与可靠性
内置过流与过热保护，能够在短路或过载情况下限制输出电流并自恢复，从而提高系统可靠性。工作温度范围覆盖工业级常用区间（-40℃ 至 +85℃），适合一般工业、通信与消费类设备。
五、封装与热管理建议
SOT-89 封装体积小但散热能力有限。建议在 PCB 设计时：
- 计算最大功耗 Pd = (Vin − 8V) × Iout，并保证实际 Pd 在器件允许值以内；
- 在器件底部与输出、地引脚周围留足铜箔，提高散热；
- 限制输入-输出电压差以降低发热，必要时增加散热板或使用更大面积铜箔。
六、典型应用
- 传感器供电与模拟前端稳压
- 小型嵌入式系统的中间电源轨
- 工业控制与通信设备中的局部稳压
- 便携或消费类电子的次级稳压需求
七、外部元件与使用注意
- 输入端建议并联一只 0.1μF 的旁路电容以滤除高频干扰；输出端建议使用 1μF~10μF 低 ESR 电容以保证稳压器稳定性（具体电容值与 ESR 范围请参照制造商数据手册）。
- 布局上应将输入/输出电容靠近芯片引脚放置，走短而粗的电源与地回流路径。
- 如需更精确的输出精度、低压差或更高效率，请考虑替代器件或配合开关升降压模块。
以上为 NJM78L08UA-TE1 的产品概述与实际应用建议。如需原厂典型曲线、引脚定义或完整电气特性表，请参阅 NISSHINBO 官方数据手册以获取详细参数和测试条件。

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.
