| 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.

PARAMETER Output Voltage Line Regulation Load Regulation (Note 1) Dropout Voltage (Note 2) Current Limit Thermal Regulation Ripple Rejection SYM Vo TEST CONDITION Io=10mA,Tj=25C Io=10mA Io=10mA,4.75V Temperature Stability Long Term Stability RMS Output Noise 1 Note 1 : Low duty cycle pulse testing with Kelvin connections are required in order to maintain accurate data. Note 2 : Drop-out 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. 2-2 Rev. 1.1 10/30/00 US1010-25 PIN DESCRIPTIONS PIN# PIN SYMBOL 1 Gnd 2 3 Vout Vin Pin Description Gnd pin. This pin must be connected to GND plane using a low inductance short connection. 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. Input pin of the regulator.
