Data and specifications subject to change without notice.

DESCRIPTION

The APU8831 device is an efficient linear voltage regula-

tor 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 shut-

down.

The APU8831 is available in fixed and adjustable output

voltage versions in a small SOT-23 5-Pin package.
