Technology Licensed from International Rectifier  
APU1205  
300mA ULTRA LOW DROPOUT POSITIVE  
ADJUSTABLE AND FIXED REGULATORS  
DESCRIPTION  
FEATURES  
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.  
Stable with 2.2uF Ceramic Capacitor  
2% Voltage Reference Accuracy  
Only 270mV Dropout at 300mA  
and 170mV Dropout at 150mA  
5uA Quiescent Current in Shutdown  
Current Limit and Thermal Shutdown  
Logic Input Enable Pin  
The APU1205 is available in fixed and adjustable  
output voltage versions in a small SOT-23 5-Pin package.  
RoHS Compliant & Halogen-Free  
SOT-23-5L & SOT-23-5LR Package
