EC3111

300mA High-PSRR Low Dropout Voltage

Linear Regulators

General Description

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/TSOT23-5L/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.
