EC3111中文资料300mA High-PSRR Linear Regulator数据手册E-CMOS规格书

描述 Description

 The EC3111 is a 300mA, low dropout and low noiselinear regulator with high ripple 

rejection ratio and fast turn-on time. It has fixed output  voltage ranging from 1.1V to

4.8V.The EC3111 includes  a voltage reference unit, an error amplifier, resistor  net for voltage setting, a current limit circuit and a chip enable circuit. These  ICs perform with low dropout voltage and a chip enable function(SOT23-5L/TSOT23-5L/SC70-4L/SC70-5L/DFN 6L package only).

 The EC3111 works well with low ESR ceramic  capacitors, suitable for portable RF and wireless battery-powered applications with stringent space requirements and demanding performance. It also offers ultra low noise output and has low quiescent current.
