n PIN DESCRIPTION  
VOUT PIN - Output pin.  
GND PIN - Power GND.  
VIN PIN  
- Power Supply Input.  
n APPLICATION INFORMATIONS  
A 1mF (or greater) capacitor is required between  
the AIC1739 output and ground for stability.  
Without this capacitor the part will oscillate. Even  
though most types of capacitor may work, the  
equivalent series resistance (ESR) should be held  
to 5W or less if Aluminum electrolytic type is used.  
Many Aluminum electrolytics have electrolytes  
that freeze at about -30°C, so solid tantalums are  
recommended for operation below -25°C. The  
value of this capacitor may be increased without  
limit.  
A 0.1mF capacitor (or greater) should be placed  
from the AIC1739 input to ground if the lead  
inductance between the input and power source  
exceeds 500nH (approximately 10 inches of trace).
