800mA LOW DROPOUT POSITIVE
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.

PIN DESCRIPTIONS
PIN#
1
PIN SYMBOL PIN DESCRIPTION
Gnd Ground pin. This pin must be connected to ground plane using a low inductance short
connection.
2
VOUT
The output of the regulator. This pin is also connected to the tab of the package. An output
capacitor must be connected to this pin to insure stability of the regulator.
3 VIN Input pin of the regulator. Typically a large storage capacitor is connected from this pin to
ground to insure that the input voltage does not sag below the minimum dropout voltage
during the load transient response. This pin must always be 1.3V higher than VOUT in order
for the device to regulate properly.
