US1010-25

US1010-25 1A LOW DROPOUT POSITIVE FIXED OUTPUT REGULATOR FEATURES Guaranteed < 1.3V Dropout at Full Load Current Fast Transient Response 1% Voltage Reference Initial Accuracy Built-in Thermal Shutdown Available in SOT-223 & D-PAK and a new Power Flex Surface Mount Packages DESCRIPTION PRELIMINARY DATASHEET APPLICATIONS Low Voltage IC supply Applications PC Clock Supply Voltage The US1010-25 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 as well as generating clock supply for the PC applications. The US 1010 is guaranteed to have <1.3V drop out at full load current making it ideal to provide well regulated with 3.8V 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.
