General Description

The SS8046 positive 3.3V voltage regulator features

the ability to source 2A of output current. The dropout

voltage is 0.5V at 2A output current. The typical qui-

escent current is 5mA. Furthermore, the quiescent

current is smaller when the regulator is in the dropout

Familiar regulator features such as over-temperature

and over-current protection circuits are provided to

prevent the device from being damaged by abnormal

the output when needed.
