TLV70012DDCR 是德州仪器(Texas Instruments)推出的一款高性能线性稳压器(LDO),专为低功耗应用设计。该稳压器采用SOT-23-THIN封装,它结合了出色的电气性能和高度集成的设计理念,适用于需要稳定和高效电压供应的各种电子设备。TLV70012DDCR 提供了一个固定输出电压 1.2V,最大输出电流可达 200mA,能够满足多种低电源电流应用的需求。
TLV70012DDCR 的输入电压范围为 1.5V 至 5.5V,最大输入电压达到 5.5V。其在200mA输出电流下的电压降(Vdrop)最大为0.25V,确保了在高输出电流时依然能够保持良好的电源效率。同时,器件的静态电流(Iq)仅为 55µA,意味着即使在低负载情况下,整体功耗也较低,这在电池供电的应用中尤为重要。
本稳压器还具备卓越的电源抑制比(PSRR)性能,其 PSRR 在1kHz频率下可达68dB,能够有效抑制输入端的电压波动,为整个电路提供稳定的电源电压。此外,TLV70012DDCR 集成了多种保护功能,包括过流、超温、反极性和欠压锁定(UVLO),这极大地提高了器件的可靠性和安全性。
TLV70012DDCR 适用于多种应用场景,包括但不限于:
TLV70012DDCR 还具备使能控制特性,能够根据外部信号来启用和禁用输出。这项特性为设计师提供了更多的灵活性,使他们可以根据应用场景智能地管理功耗,有效延长产品的使用时间。
TLV70012DDCR 的工作温度范围为 -40°C 至 125°C,使其适合在高温和低温环境中工作,为各种应用提供了广泛的适用性。无论是在室内电子设备还是严酷的工业环境中,这款稳压器都能保持稳定的电源输出。
TLV70012DDCR 采用 SOT-23-THIN 封装,这种小型封装为设计师节省了电路板空间,有助于总体设计的紧凑性。足够的引脚排列使其易于在各种电路设计中集成。
在当今电子产品日益小型化和低功耗的背景下,德州仪器的 TLV70012DDCR 线性稳压器凭借其高效能、可靠性和丰富的保护功能,成为电子设计工程师的理想选择。无论是移动设备、传感器,还是工业应用,这款 LDO 都提供了稳定的电源解决方案,确保终端应用的卓越性能和长期稳定性。
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.
