General Description
The SS8047 positive 2.5V voltage regulator features
the ability to source 1A of output current. The typical
quiescent current is 0.6mA.
Familiar regulator features such as over-temperature
and over-current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.
