11月25日由ASPENCORE主办的“2025年度全球电子成就奖”颁奖典礼在深圳隆重举行，润石科技今年推出的首款电压跟随型LDO RS3011-Q1获评全球电子成就奖之“年度电源管理/电压转换器产品”奖项！
电压跟随型低压差线性稳压芯片(即LDO)是一类功能比较特殊的LDO稳压器，其输出电压(VOUT)直接跟踪或者说“跟随”其参考输入电压(VREF)，即VOUT=VREF。这种功能的LDO通常使用于给汽车非车载传感器或者其他非板载模块供电，以保证传感器工作电压的精准和稳定，并可防止因电缆断裂而导致的对地短路或电池短路时损坏板载元件。
RS3011-Q1采用车规级工艺，最大化安全余量设计，具有-40V到45V的输入耐压承受能力，并提供最大300mA的输出电流，满足汽车电子应用场景的高可靠性要求，在轻载下自身消耗电流80μA，可提供最大300mA的输出电流能力、最大4mV跟踪误差输出；高电源纹波抑制能力PSRR达78dB@100Hz；且具有反极性保护、输出短路到地保护、输出短路到电源保护、输出脚感性负载钳位保护等。
该款主要是针对汽车电子应用领域的特殊电路保护设计，也可以用于其他需要实时可调电源的供电系统，比如透过控制DAC直接给ADJ脚需要的输出电压，实现高精度的实时可调的供电电源。内部背靠背PMOS拓扑，无需使用外部二极管即可实现反极性条件下的保护，特别适合需要防反接防倒灌功能的电路。
可提供标准ESOP8封装，与市场常用型号完全兼容，并提供带使能和不带使能两种版本，以满足不同产品系统的设计需求。

How to Use a Multiphase Boost Converter
When the required system voltage exceeds the available supply voltage, a boost converter is typically an ideal solution. However, conventional standard boost topologies are not the only option. In certain application scenarios, phase-shifted multiphase boost converters can deliver superior performance: these converters achieve higher efficiency under heavy-load conditions while significantly reducing the required capacitance values for both the input and output stages.
GigaDevice announced that its 1.2V ultra-low-power SPI NOR Flash GD25UF series has now expanded its capacity lineup from 8 Mb to 256 Mb. This move precisely addresses the diversified storage requirements across a wide range of applications, from high-performance AI computing to low-power battery-powered devices. Leveraging its significant advantages of low voltage and ultra-low power consumption, this product provides robust support for rapidly growing emerging markets such as wearable devices, smart headphones, AI ASIC platforms, and medical electronics. While substantially extending the battery life of end devices, it will also further drive product development toward edge AI and extreme miniaturization, accelerating the innovative upgrade of next-generation smart terminals.
