EC3121

300mA 2CH Low Dropout Voltage

Linear Regulators

General Description

The EC3121 is a low noise and high accuracy,

high ripple rejection ratio, low dropout, dual CMOS

LDO voltage regulators with enable function. The EN

function allows the output of each regulator to be

turned off independently, resulting in greatly reduced

power consumption.

The current limit of EC3121 is over 350mA per

channel and also operates as a short protection for

the output current limiter. The output voltage for each

regulator is set independently by metal trimming.

The EC3121 comes with low design cost and

outstanding output stability and its compatibility of

working

with

low

ESR

ceramic

capacitors

is

undoubted.

This

high

level

output

stability

is

maintained even during frequent load fluctuations, due

to the excellent transient response performance and

high PSRR achieved across a broad range of

frequency, so these ICs are suitable for hand-held

communication equipment power supply.
