DESCRIPTION

A6618

series is a group of positive voltage output,

low power consumption, low dropout voltage

regulator.

A6618

can provide output value adjustable from 0.8V

to 5.0V.

A6618

includes high accuracy voltage reference,

error amplifier, current limit circuit and output driver

module with discharge capability.

A6618 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. It uses trimming technique to guarantee output voltage accuracy within ±2. And it also provides foldback short-circuit protection, thermal protection and output current limit function.

The A6618 is available in SOT-25 package.
