300mA High-PSRR Low Dropout Voltage
Linear Regulators
EC3111
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.
