TPS7A2036PDBVR 是一款固定输出的线性稳压器(LDO),由 TI(德州仪器)推出,面向对噪声、纹波抑制和低静态功耗有较高要求的供电场合。该器件在 SOT-23-5 小封装内提供 3.6V 正向固定输出,最大输出电流可达 300mA,适合便携、低功耗及模拟前端电源等应用。
该器件设计强调低压差、低噪声与低静态功耗的平衡。140mV 的压差(在 300mA 输出时)说明在高负载条件下仍能保持较小的输入与输出电压差,利于延长电池使用时间或提高系统效率。15μA 的静态电流意味着在待机或轻载情况下,整体系统的静态损耗极低,适合电池供电系统。65dB@100Hz 的 PSRR 和 10μVrms 的输出噪声使该 LDO 特别适合对噪声敏感的模拟和射频电路、电源参考以及 ADC 驱动电源。
请注意:实际的输入电压裕度、启动性能及稳定性与外部元件(如输入/输出电容)有关,设计时应参照器件应用规范进行布局与选型。
该器件集成了多项保护与控制机制,以保证系统安全可靠运行:
这些功能使器件在复杂电源管理场景中既安全又易于控制。
TPS7A2036PDBVR 采用 SOT-23-5 小型封装,适合空间受限的 PCB 设计。虽然封装小巧带来布局便利,但在高输出电流和高功耗工况下需要注意散热:
典型应用:
设计要点:
TPS7A2036PDBVR 是一款定位明确的固定输出 LDO,兼顾低压差、低噪声和低静态功耗,且内置完整的保护与控制功能,适合对电源质量与功耗要求高的应用场景。其 SOT-23-5 封装利于空间受限的设计,但同时需在 PCB 布局与散热方面给予关注,以确保在 300mA 输出和较大压差条件下稳定可靠运行。若需进一步参数(如精确输出容差、动态性能、输入/输出电容推荐及引脚定义等),建议参考 TI 官方数据手册和应用说明以获得完整设计指导。

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.
