SUL6103 3A 0.8V High PSRR(60dB@1KHz) Low Noise Ultra Low Dropout Linear Regulator

PublishTime： 2025-09-18 Manufacturer： SUNTEK Type： Datasheet Language： English

SUL6103是一款高电流（3A）的CMOS低压差线性稳压器（LDO），提供超快的瞬态响应、高PSRR、超低 dropout 电压、高输出电压精度、超低噪声和高的输出电流能力。该器件的输出电压可通过引脚选择（最大=3.95V），无需外部电阻即可实现PCB布局，从而降低整体成本。为了实现更高的输出电压，设计人员可以使用外部电阻分压器。最低输入供电电压为1.1V，使其易于使用。通过使用NMOS通孔元件，它在应用中提供了几个优点。与PMOS通孔元件相比，输出电容器对环路稳定性的影响较小。与标准PMOS稳压器相比，在非常低的Vin应用中，dropout电压可以非常低。出色的PSRR、低噪声、超负载瞬态响应和高输出电流能力使其非常适合为功率噪声敏感电路的电源供电，如SerDes、DACs、ADCs和RF组件。此外，SUL6103非常适合为数字负载供电，如FPGAs、DSPs和ASICs。SUL6103的高性能特性确保了最佳的系统性能。
