KEY FEATURES  
DESCRIPTION  
The LX8117/8117A/8117B series are positive  
Low Dropout (LDO) regulators. At the designed  
maximum load current, the LX8117 series  
differential voltages down to 1V.  
Most regulator circuit designs include output  
capacitors with values in the range of tens to

lower at 0.8A (LX8117A 1.3V @ 1A). The  
dropout voltage decreases with load current.  
An adjustable output voltage version of the  
LX8117/17A/17B is available, as well as to as much as 10 percent of their output as a

designed for use as a component of active  
termination networks for the SCSI bus. On-chip load, increasing power-use efficiency and  
trimming of the internal voltage reference allows  
specification of the initial output voltage to  
LX8117/17A/17B typically requires at least  
10µF of output capacitance for stable operation.
