1.  Overview 
1.1  Description 
 The voltage regulators are designed as fixed-voltage regulator for a wide variety of applications   
  Including local,on-card regulation. Although designed primarily as a fixed voltage regulator,   
these devices can be used with external components to obtain adjustable voltages and currents   
 
1.2  Features   
•    Output current in excess of 1.0A 
• No external components required 
•    Output voltages (5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V) 
•    Internal Thermal shutdown and SOA protection 
• Output voltage offered in 4% Tolerance 
• Pb-Free Packages are available 
• High ESD Level (HBM>8,000V, MM>800V)

 The input voltage must  remain  typically 2.0V above the output voltage  even during the  
 low point on the ripple voltage. 
  
 • CI is required if regulator is located an appreciable distance from power filter.  
 • Co improves transient response. Value of  ≤0.1㎌  could cause instability.
