具有使能功能的 1A、10V、低压降稳压器

LP38690 和 LP38692 低压降互补金属氧化物半导体 (CMOS) 线性稳压器的输出容差很小（典型值为 2.5%）并且压降极低（负载电流为 1A、VOUT = 5V 时为 450mV），通过使用超低等效串联电阻 (ESR) 陶瓷输出电容提供出色的交流性能。 晶圆级小外形无引线 (WSON)、小外形尺寸晶体管 (SOT)-223 以及 TO-252 封装的热阻较低，即使在高温环境中也可实现满电流运行。 P 型金属氧化物半导体 (PMOS) 功率晶体管的使用意味着无需直流基极驱动电流对其进行偏置，因此无论负载电流、输入电压或者运行温度为何，接地引脚电流均可保持在 100μA 以下 • 宽输入电压范围（2.7V 至 10V）\n• 2.5% 输出精度 (25°C)\n• 低压降电压： 1A 时为 450mV （典型值，5 VOUT）\n• 精密（已调整）带隙基准\n• 可保证 –40°C 至 +125°C 温度范围的技术规格\n• 1µA 关闭状态静态电流\n• 热过载保护\n• 折返电流限制\n• 3 引脚 TO-252、5 引脚小外形尺寸晶体管 (SOT)-223 和 6 凸点晶圆级小外形无引线 (WSON) 封装\n• 使能引脚 (LP38692)\n• 接地引脚电流：满载时为 55µA（典型值）\n• 精密输出电压：精度为 2.5%（25°C 时）;
