基于LM4041A12型号 1.2V 精密微功耗并联电压参考，0.1% 精确度
描述 The LM4041 series of shunt voltage references are versatile, easy-to-use references suitable for a wide array of applications. They require no external capacitors for operation and are stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and a low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4041 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications. The LM4041 is available in a fixed (1.225 V nominal) or an adjustable version (which requires an external resistor divider to set the output to a value between 1.225 V and 10 V). Packaged in space-saving SC-70 and SOT-23-3 and requiring a minimum current of 45 µA (typ), the LM4041 also is ideal for portable applications. The TO-92 package also is available for through-hole packaging needs. The LM4041xI is characterized for operation over an ambient temperature range of -40°C to 85°C. The LM4041xQ is characterized for operation over an ambient temperature range of -40°C to 125°C. 特性 1.225-V Fixed and Adjustable Outputs (1.225 V to 10 V) Tight Output Tolerances and Low Temperature Coefficient Max 0.1%, 100 ppm/°C — A Grade Max 0.2%, 100 ppm/°C — B Grade Max 0.5%, 100 ppm/°C — C Grade Max 1.0%, 150 ppm/°C — D Grade Low Output Noise . . . 20 µVRMS (Typ) Wide Operating Current Range . . . 45 µA (Typ) to 12 mA Stable With All Capacitive Loads; No Output Capacitor Required Available in Industrial Temperature: -40°C to 85°C Extended Temperature: -40°C to 125°C Applications Data-Acquisition Systems Power Supplies and Power-Supply Monitors Instrumentation and Test Equipment Process Control Precision Audio Automotive Electronics Energy Management/MeteringBattery-Powered Equipment 相关料号推荐：LM4041DYM3-1.2-TR 相关终端应用 Circuit Breaker 三相 UPS 交流电源、直流电源和电子负载 冰箱和冰柜 割草机 医疗 PSU 单相 UPS 吸尘器 咖啡机 商用 DC-DC 商用 DIN 导轨电源 商用电信整流器 商用电池充电器 商用网络和服务器 PSU 太阳能 - 微型逆变器 太阳能 - 组串式逆变器 家用水泵和风扇 家电压缩机 工业 AC-DC 无管式空调室内系统 无管式空调室外装置 无绳手持园艺工具 无绳电动工具 服务型机器人 机器人割草机 油烟机 洗衣机和干衣机 混料器、搅拌器和食品加工机 由市电供电的工具 电子病床和床控制器 真空机器人 风扇
