TPS7A2012PDBVR 是由德州仪器(Texas Instruments)制造的高性能线性稳压器(LDO),适用于各种需要稳定和低噪声电源的应用。以下是对此产品的详细介绍。
TPS7A2012PDBVR 提供了一个固定输出电压为 1.2V 的稳定电源,适用于各种数字和模拟电路。其最大输出电流可达 300mA,满足中等功率应用的需求。
该稳压器具有低dropout电压(最大值为 0.355V @ 300mA),这意味着在输入电压接近输出电压时,仍能维持稳定的输出,这对于节能和提高系统效率非常重要。
TPS7A2012PDBVR 拥有出色的功率供应抑制比(PSRR),在频率范围从 100Hz 到 1MHz 时,PSRR 可达 65dB ~ 40dB。这确保了即使输入电源存在噪声,也能提供清洁和稳定的输出。
该稳压器内置多种保护功能,包括过流保护、超温保护和欠压锁定(UVLO)。这些功能可以防止设备在异常条件下受到损害,提高系统的可靠性和安全性。
在静态状态下,TPS7A2012PDBVR 的静态电流仅为 15µA,这对于低功耗应用来说是非常理想的。同时,最大供电电流仅为 2mA,进一步减少了能耗。
该稳压器的工作温度范围从 -40°C 到 125°C,这使得它可以在各种环境条件下运行,适用于工业、汽车和其他严苛环境中的应用。
采用 SOT-23-5 封装,TPS7A2012PDBVR 非常适合空间有限的设计,能够满足现代电子产品对小型化和高集成度的需求。
TPS7A2012PDBVR 可用于为微处理器、FPGA、ASIC 等数字芯片提供稳定的电源,确保这些设备在各种操作条件下运行稳定。
对于需要低噪声和高稳定性的模拟电路,如运算放大器、数据转换器等,TPS7A2012PDBVR 提供了理想的电源解决方案。
在无线通信设备中,如手机、无线路由器等,TPS7A2012PDBVR 可以为射频和基带处理器提供清洁的电源,从而提高通信质量。
由于其宽工作温度范围和多重保护功能,TPS7A2012PDBVR 也非常适合用于汽车电子系统,如娱乐系统、导航系统等。
为了优化性能,建议在输入端添加适当的滤波元件,如电容和电感,以减少噪声和振荡。
在输出端添加一个小值的电容可以帮助稳定输出电压并减少噪声。
通过使能引脚,可以实现对稳压器的启用和禁用,这在某些应用中可以帮助实现低功耗模式。
尽管该稳压器具有超温保护,但在高功率应用中仍应注意散热设计,以确保设备在正常工作范围内运行。
TPS7A2012PDBVR 是一款高性能、低dropout、低噪声的线性稳压器,适用于广泛的应用场景。其优秀的PSRR、多重保护功能和低静态电流使其成为现代电子系统中的理想选择。通过合理的设计和使用,这款稳压器可以帮助您构建更加可靠、效率更高的电子产品。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
