【产品】在整个温度范围内电流能力达3A的低压差稳压器LT1764,专为大电流负载而设计
LT1764是华冠半导体推出的一款高电流、低成本、低压差稳压器。该稳压器在满载时具有450mV的低压差电压和极低的接地电流。该芯片是专为大电流负载而设计,还可用于低电流、低压差关键系统。在这些系统中,它的压差电压和接地电流值是重要属性。该稳压器除了在温度、线路和负载调节范围内具有±2%的总精度外,还具有对输入电压浪涌和输出负载电流变化非常快速的瞬态恢复功能。
LT1764具有可调输出电压,可以通过两个外部电阻器将其设置为1.24V至15V之间的电压。此外,该器件还具有全面保护功能,可防止出现过流故障、输入极性反接、引线插入反接和过热操作。该芯片中有一个TTL逻辑使能 (EN) 引脚可用于关断稳压器。在不使用时,通过将EN连接到输入 (IN)可将芯片设置为连续工作。
LT1764采用标准的5引脚TO-263和TO-252封装,封装和引脚配置如图1所示。该芯片的工作结温范围为 -40°C 至 +85°C,典型应用电路如图2所示,主要应用于处理器外围设备和I/O电源、高效“绿色”计算机系统、汽车电子、高效线性电源、电池供电设备、PC附加卡以及开关电源的高效后置稳压器等领域。
