FIXED 1.8V REGULATOR
DESCRIPTION
The IRU1117-18 is a low dropout three-terminal fixed out-
put regulator with minimum of 800mA output current ca-
pability. This product is specifically designed to provide
well regulated supply for low voltage IC applications as
well as generating clock supply for PC applications. The
IRU1117-18 is guaranteed to have <1.2V dropout at full
load current making it ideal to provide well regulated with
3.8V input supply. The IRU1117-18 is specifically de-
signed to be stable with low cost aluminum capacitors
while maintaining stability with low ESR tantalum caps.
