US1010-33

US1010-33 1A LOW DROPOUT POSITIVE FIXED OUTPUT REGULATOR FEATURES Guaranteed < 1.3V Dropout at Full Load Current Fast Transient Response 1% Output Voltage Initial Accuracy Built-in Thermal Shutdown Available in SOT-223, D-PAK , Power Flex and 8 pin SOIC Surface Mount Packages DESCRIPTION PRELIMINARY DATASHEET APPLICATIONS VGA & Sound Card Applications Standard 3.3V Chip-Set and Logic Applications The US1010-33 is a low dropout three terminal fixed output regulator with minimum of 1A output current capability. This product is specifically designed to provide well regulated supply for low voltage IC applications such as VGA , sound & DVD cards. The US 1010 is guaranteed to have <1.3V drop out at full load current making it ideal to provide well regulated with 4.75V to 7V input supply. The US1010 is specifically designed to be stable with low cost Aluminimum capacitors while still maintains stability with low ESR tantalum caps as well.
