TPRT9013-12GB 是 TECH PUBLIC(台舟电子)推出的一款低压差线性稳压器(LDO),为固定输出型器件,采用 SOT-23-5 小封装,面向对低噪声、高抑制比和低静态电流有要求的便携与嵌入式电源应用。器件输出为正极性、单通道,带使能(Enable)功能,便于系统节能与电源管理。
TPRT9013-12GB 在 1kHz 频段提供约 70dB 的 PSRR,加上 50µVrms 的低输出噪声,使其非常适合为 ADC 前端、RF 前端、参考电路以及对噪声敏感的放大器供电。60µA 的静态电流有利于延长电池寿命,带使能脚可在不工作时通过外部逻辑关闭稳压器以进一步节省功耗。SOT-23-5 小封装适用于空间受限的移动设备与物联网终端。
线性稳压器的功耗主要由输入输出压差与负载电流决定:Pd = (Vin - Vout) × Iout + Iq × Vin。举例:当 Vin = 7V、Vout = 1.2V、Iout = 500mA 时,器件耗散功率约为 2.9W——对于 SOT-23-5 小封装而言通常超过安全散热范围,可能导致过热或降额工作。因此在系统设计中应注意:
TPRT9013-12GB 提供 1.2V、最大 500mA 输出的固定 LDO 解决方案,具备低静态电流、良好 PSRR 与低噪声特性,适合电池供电与对噪声敏感的应用。但在高输入电压与大输出电流工况下需特别注意功耗与封装散热限制。欲获得详细电气特性、引脚排列与典型应用电路,请参照 TECH PUBLIC 的完整产品规格书与评价资料。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
