General Description
The G903 positive 3.3V voltage regulator features the
ability to source 600mA of output current with a
dropout voltage of typically 0.65V. A low quiescent
current is provided. The typical quiescent current is
0.3mA.
Familiar regulator features such as over temperature
and over current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.
