ADJUSTABLE AND FIXED REGULATORS  
DESCRIPTION  
FEATURES  
SOT-23 Package  
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.  
Stable with 2.2µF Ceramic Capacitor  
1% Voltage Reference Accuracy  
Only 270mV Dropout at 300mA  
and 170mV Dropout at 150mA  
5µA Quiescent Current in Shutdown  
Current Limit and Thermal Shutdown  
Logic Input Enable Pin  
RoHS Compliant  
The APU1205 is available in fixed and adjustable output  
voltage versions in a small SOT-23 5-Pin package.  
APPLICATIONS
