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 55碌A. In the shut-
down mode, the maximum supply current is less than
1碌A. 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鈥檚.
