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.
