DESCRIPTION
The APU1205 device is an efficient linear voltage regula-
tor with better than 1% initial voltage accuracy, very low
dropout voltage and very low ground current designed
especially for hand held, battery powered applications.
Other features of the device are: TTL compatible enable/
shutdown control input, current limiting and thermal shut-
down.
The APU1205 is available in fixed and adjustable output
voltage versions in a small SOT-23 5-Pin package.
