APU1205
300mA ULTRA LOW DROPOUT POSITIVE
ADJUSTABLE AND FIXED REGULATORS
DESCRIPTION
The APU1205 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 APU1205 is available in fixed and adjustable
output voltage versions in a small SOT-23 5-Pin package.
