General Description
The G9131 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23 pack-
age. The supply current at no-load is 90µA. An over
temperature protection circuit is built-in in the G9131
to prevent thermal overload. These power saving fea-
tures make the G9131 ideal for use in the bat-
tery-powered applications such as notebook com-
puters, cellular phones, and PDA’s.
Applications
Cordless Phones
PDAs
