FEATURES  
DESCRIPTION  
D
FIXED AND ADJUSTABLE VERSIONS  
2.85V MODEL FOR SCSI-2 ACTIVE  
TERMINATION  
The REG1117 is a family of easy-to-use three-terminal  
voltage regulators. The family includes a variety of fixed-  
and adjustable-voltage versions, two currents (800mA and  
1A) and two package types (SOT-223 and DDPAK). See  
the chart below for available options.  
D
D
OUTPUT CURRENT:  
REG1117: 800mA max  
Output voltage of the adjustable versions is set with two  
external resistors. The REG1117 low dropout voltage  
allows its use with as little as 1V input-output voltage  
differential.  
REG1117A: 1A max  
OUTPUT TOLERANCE: + 1% max  
DROPOUT VOLTAGE:  
REG1117: 1.2V max at I = 800mA  
D
D
O
Laser trimming assures excellent output voltage accuracy  
without adjustment. An NPN output stage allows output  
stage drive to contribute to the load current for maximum  
efficiency.
