NJM79L15SU3-TE1 产品概述
一、产品简介
NISSHINBO 的 NJM79L15SU3-TE1 是一款固定输出的线性负电压稳压器（LDO），提供典型的 -15V 输出（输出极性为负极），单通道设计，封装为 SOT-89-3。器件集成过流保护与过热保护，适用于需要稳定负电源的小功率系统。
二、主要性能参数
- 输出类型：固定（负电压，-15V）
- 最大输出电流：100 mA
- 工作电压（输入绝对值）：30 V（最大）
- 压差（Dropout）：2 V @ 100 mA
- 静态电流（Iq）：3.5 mA
- 电源纹波抑制比（PSRR）：64 dB @ 120 Hz
- 输出噪声：340 µV（典型）
- 保护功能：过流保护、过热保护
- 工作温度范围：-40 ℃ ~ +125 ℃（Ta）
- 封装：SOT-89-3，单通道
三、电气特性解读
压差 2 V@100 mA 意味着在满载条件下，输入端电压幅值需比输出幅值至少高出 2V（例如欲得到 -15V 输出，输入端电压在满载时应为约 -17V 或更负）。静态电流 3.5 mA 有利于降低静态功耗但对电池供电系统仍需考虑待机损耗。PSRR 64 dB（120 Hz）表明对工频纹波有较强抑制能力，配合良好去耦可获得低噪声负电源。
四、典型应用场景
- 运算放大器与仿真电路的负电源
- 仪表与传感前端需要对称供电的场合
- 便携或工业控制设备中低电流负轨供电
- 音频、通信中的负电源稳压与噪声要求中等的场合
五、封装与布局建议
SOT-89-3 封装散热能力有限，持续 100 mA 输出且存在较大压降时器件功耗 P = (|Vin| - |Vout|) × Iout 可能显著上升。建议：
- 在 PCB 上为引脚及 GND 提供较大铜箔面积以利散热；必要时增加散热铜簇或散热垫。
- 输入、输出端并接去耦电容（例如 1 µF ～ 10 µF 陶瓷或钽电容），同时在输入端加一个旁路电容以抑制干扰，输出端电容有助于稳态与瞬态性能。
- 布局上输入、输出走线尽量短、粗，地线采用单点或短回路，以降低回路噪声。
六、使用注意事项与采购信息
- 使用时检查输入电压极性与绝对值，避免超过最大工作电压 30 V。
- 在高压差或高负载条件下注意器件温升，利用 PCB 散热措施或降低负载以防热关断触发。
- 型号：NJM79L15SU3-TE1，品牌：NISSHINBO，封装：SOT-89-3。采购时确认详细规格书以校核极限参数、外形引脚分配及推荐外部元件要求。
如需参考典型电路图、实际热阻计算或基于具体电源条件的选型建议，可提供输入电压、负载情况与工作环境，我可进一步给出优化建议。

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.
