A1085

AiT Semiconductor Inc. www.ait-ic.com A1085 3A LOW-DROPOUT POSITIVE VOLTAGE REGULATOR THERMAL SHUTDOWN AND CURRENT LIMIT FUNCTIONS DESCRIPTION The A1085 is a series of low dropout three terminal regulators with a dropout of 1.3V at 3A load current. Other than a fixed version (VOUT=1.8V, 2.5V, 3.3V, 5V), The A1085 has an adjustable version, which can set the output voltage with only two external resistors. The A1085 offers thermal shut down and current limit functions, to assure the stability of chip and FEATURES Provide Fixed Version and an Adjustable Version, Output Value can be customized on command. Maximum Output Current: 3A Output Voltage Accuracy within ±2% Range of Operation Input Voltage: Max 15V Line Regulation: 0.2% (Typ.) Load Regulation: 0.4% (Typ.) Environment Temperature: -50oC~+140oC Available in TO-252, TO-263-2 and TO-263-3 power system. And the A1085 uses trimming technique to guarantee output voltage accuracy within ±2% Package APPLICATION Power Management for Computer Mother The A1085 is available in TO-252, TO-263-2 and TO-263-3 package.
