General Description
The G930/G931 positive 3.5V voltage regulator fea-
tures the ability to source 400mA of output current
with a dropout voltage of typically 0.8V over the en-
tire operating temperature range. A low quiescent
current is provided over the entire output current
range. The typical quiescent current is 0.6mA. Fur-
thermore, the quiescent current is smaller when the
regulator is in the dropout mode (V
IN
< 3.5V).
Familiar regulator features such as over temperature
and over current protection circuits are provided to
prevent it from being damaged by abnormal operating
conditions.
