UNISONIC TECHNOLOGIES CO., LTD UT7500 Preliminary CMOS IC HIGH DRIVER REGULATOR DESCRIPTION The UTC UT7500 series is a low voltage regulator implemented by CMOS technology which is composed of a three-terminal high current. The input voltage for it is allowed as high as 24V and the output voltage are fixed at 3.0V、3.3V and 5.0V. Besides, it delivers 100mA output current. Other outstanding features of UTC UT7500 include low voltage drop and low quiescent current. When being used with external components, UTC UT7500 can obtain variable voltages and currents. UTC UT7500 series is very suitable for applications, such as battery-powered equipment, communication equipment and audio/video equipment. 1 FEATURES SOT-89 * Very Low Power Consumption * Very Low Voltage Drop * Very Low Temperature Coefficient * Up to 24V Input Voltage * 100mA @PD≤250mW Output Current * Tolerance ±3% * Halogen Free ORDERING INFORMATION Ordering Number Package UT7500G-xx-AB3-C-R SOT-89 Note: Pin Assignment: I:VIN O:VOUT G:GND xx: Output Voltage, refer to Marking Information.
