IRU1117-18(PbF) 1www.irf.com TYPICAL APPLICATION 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. 800mA LOW DROPOUT POSITIVE FIXED 1.8V REGULATOR Figure 1 - Typical set-up of the IRU1117-18 in a 3.3V to 1.8V regulator application.

Typical values refer to TJ=25 C. ELECTRICAL SPECIFICATIONS Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data. Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain regulation at VOUT. It is measured when the output voltage drops 1% below its nominal value.

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. 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. BLOCK DIAGRAM Figure 2 - Simplified block diagram of the IRU1117-18.
