General Description

The G920 is a low supply current, low dropout linear

regulator that comes in a space saving SO-8 package.

The supply current at no-load is 55µA. In the shut-

down mode, the maximum supply current is less than

1µA. operating voltage range of the G920 is from 3.6V

to 6.5V. The over-current protection limit is set at

250mA typical and 150mA minimum. An over-tem-

perature protection circuit is built-in in the G920 to

prevent

thermal

overload.

These

power

saving

features make the G920 ideal for use in the bat-

tery-powered applications such as notebook com-

puters, cellular phones, and PDA’s.
