RS7103
Low Power 300mA CMOS LDO with Enable
概述
该RS7103是工作在输入电压范围为+ 2.5V至+ 9.0V ,并提供了一个低压差线性稳压器
300mA output current.
高精度输出电压预置为一个内部调整电压为2.5V或3.3V 。其他输出电压可以
mask‐optioned from 1.5V to 5.0V with 100mV increment.
的RS7103由一个1.25V的参考,一个误差放大器,一个P沟道传输晶体管,和一个使能/禁用逻辑
circuit. Other features include short‐circuit protection, soft start function, and thermal shutdown protection. The RS7103
device is available in SOT‐25 package.
