RS7300
600mA Adjustable & Fixed Voltage LDO Linear Regulator
概述
在RS7300系列是工作在输入电压范围为+ 2.4V至+ 7.0V和低压差线性稳压器
delivers 600mA output current.
的RS7300是两种类型,固定输出电压型和可调输出电压类型。固定输出
电压型预置在一个内部调整电压1.8V ,2.5V或3.3V 。其他选择1.0V , 1.2V , 1.5V , 1.8V , 2.0V ,
2.85V, 3.0V, 3.3V, 3.6V and 5.0V are available by special order only. The output voltage range of the adjustable type is from
1.25V to 5V.
The RS7300 (ADJ type) consists of a 1.25V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other
功能包括短路保护和热关机保护。
The RS7300 (Fixed type) consists of a 0.95V bandgap reference, an error amplifier, and a P‐channel pass transistor. Other
features include short‐circuit protection and thermal shutdown protection. The RS7300 series devices are available in SOT‐
223, SOT‐89 and SOT‐23 packages.
