DESCRIPTION
The APU8852 device is an efficient linear
voltage regulator with better than 2% 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 shutdown.
The APU8852 is available in fixed and
adjustable output voltage versions in a small
SOT-23 5-Pin package.
