IRU1117

www.DataSheet4U.com Data Sheet No. PD94136 IRU1117 800mA LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR DESCRIPTION The IRU1117 is a low dropout, three-terminal adjustable regulator with minimum of 800mA output current capability. This product is specifically designed to provide well regulated supply for low voltage IC applications such as high speed bus termination and low current 3.3V logic supply. The IRU1117 is also well suited for other applications such as VGA and sound cards. The IRU1117 is guaranteed to have <1.2V dropout at full load current making it ideal to provide well regulated outputs of 2.5V to 3.6V with 4.75V to 7V input supply. FEATURES Guaranteed < 1.2V Dropout at 800mA Load Current Fast Transient Response 1% Voltage Reference Initial Accuracy Built-In Thermal Shutdown Available in SOT-223, D-Pak, Ultra Thin-Pak TM and 8-Pin SOIC Surface-Mount Packages APPLICATIONS VGA & Sound Card Applications Low Voltage High Speed Termination Applications Standard 3.3V Chip Set and Logic Applications TYPICAL APPLICATION D1 5V C1 10uF VI N 3 2 R1 121 IRU1117 VO U T 2.85V / 800mA C2 10uF Adj 1 R2 154 Figure 1 - Typical application of IRU1117 in a 5V to 2.85V SCSI termination regulator.
