HT7550S 是由友台半导体(UMW)出品的一款高性能线性稳压器(LDO),专为需要稳定和低噪声电源的应用场景设计。以下是对 HT7550S 的详细介绍。
HT7550S 采用 SOT-23 封装,这是一种小型化的封装形式,非常适合于空间有限但要求高性能的电子设备。SOT-23 封装不仅节省了 PCB 布局空间,还能提高设备的整体可靠性和耐用性。
HT7550S 提供了极高的输出电压稳定性和精度,即使在输入电压变化或负载电流变化的情况下,也能保持输出电压的稳定。这使得它特别适合于需要精确控制电源的应用,如无线通信设备、医疗器械、工业控制系统等。
该稳压器具有非常低的噪声特性,这对于许多对噪声敏感的应用(如音频设备、RF 模块等)来说是非常重要的。低噪声设计确保了输出信号的清晰度和质量。
尽管 HT7550S 具有高性能,但其待机电流仅为 3uA,这意味着在不使用时,它对电池或供电系统的消耗非常小。这种低待机电流特性使其非常适合于需要长时间运行但又要节省能量的设备,如便携式电子产品。
HT7550S 支持从 -40℃ 到 +85℃ 的宽工作温度范围,这使得它可以在各种环境条件下正常运行,无论是在极寒还是高温条件下,都能保持稳定的性能。
HT7550S 的低噪声和高稳定性特性使其成为无线通信设备(如手机、无线路由器、蓝牙模块等)的理想选择。
在医疗领域,精确控制电源是至关重要的。HT7550S 的高精度和稳定性使其适用于各种医疗设备,如心率监测仪、血压计等。
工业控制系统需要可靠且高性能的电源组件。HT7550S 的宽工作温度范围和低噪声特性使其成为工业自动化设备的一个不错选择。
对于需要长时间运行但又要节省能量的便携式电子产品,HT7550S 的低待机电流特性是一个显著优势。
确保输入电压不超过最大允许值(30V),以避免损坏稳压器。
虽然 HT7550S 具有良好的热特性,但在高负载或高环境温度下,仍需要进行适当的散热设计,以确保稳压器的可靠运行。
在 PCB 设计中,应尽量减少从输入到输出之间的电阻和电感,以确保最佳性能。
HT7550S 是一款功能强大、性能优异的线性稳压器,适用于各种需要稳定和低噪声电源的应用场景。其小型化封装、宽工作温度范围、低噪声特性以及高效能设计,使其成为现代电子设备中的一个理想选择。如果您正在寻找一款可靠且高性能的 LDO,HT7550S 无疑是一个值得考虑的产品。
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.
