DESCRIPTION
The |RU1117-18 is a low dropout three-terminal flxed 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
|RU1117-18 is guaranteed to have <1.2V dropout at full
load current making it ideal to provide well regulated with
3.8V input supply. The lRU1117-18 is spetyfcally de-
signed to be stable with low cost aluminum capacitors
while maintaining stability with low ESR tantalum caps.

Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and Vow required to maintain
regulation at Vow. It is measured when the output voltage drops 1% below its nominal value.
