General Description<\/h3>\n\n\n\n

The EC3111 is a 300mA, low dropout and low noise linear 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\/TSOT23-3L\/TSOT23-5L\/SC70-4L\/SC70-5L\/DFN-6L\/UDFN-4Lpackage 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.<\/p>\n\n\n\n
