PJ1084  
5 Amp Low Dropout Positive Voltage Regulator  
He PJ1084 Series are high performance positive voltage  
TO-220  
TO-263  
Tregulators are designed for use in applications requiring  
low dropout performance at full rated current, Additionally,  
the PJ1084 Series provides excellent regulation over  
variations due to changes in line, load and temperature.  
Outstanding features include low dropout performance at  
rated current, fast transient response, internal current  
limiting and thermal shutdown protection of the output  
device. The PJ1084 Series are three terminal regulators with  
fixed and adjustable voltage options available in popular  
packages.
