DESCRIPTION The LT?3080 is a 1.1A low dropout linear regulator that can be paralleled to increase output current or spread heat in surface mounted boards. Architected as a precision current source and voltage follower allows this new regulator to be used in many applications requiring high current, adjustability to zero, and no heat sink. Also the device brings out the collector of the pass transistor to allow low dropout operation —down to 350 millivolts— when used with multiple supplies. FEATURES ■ Outputs May be Paralleled for Higher Current and Heat Spreading ■ Output Current: 1.1A ■ Single Resistor Programs Output Voltage ■ 1% Initial Accuracy of SET Pin Current ■ Output Adjustable to 0V ■ Low Output Noise: 40μVRMS (10Hz to 100kHz) ■ Wide Input Voltage Range: 1.2V to 36V ■ Low Dropout Voltage: 350mV (Except SOT-223 Package) ■ <1mV Load Regulation ■ <0.001%/V Line Regulation ■ Minimum Load Current: 0.5mA ■ Stable with 2.2μF Minimum Ceramic Output Capacitor ■ Current Limit with Foldback and Overtemperature Protected ■ Available in 8-Lead MSOP, 3mm × 3mm DFN, 5-Lead DD-Pak, TO-220 and 3-Lead SOT-223 APPLICATIONS ■ High Current All Surface Mount Supply ■ High Effi ciency Linear Regulator ■ Post Regulator for Switching Supplies ■ Low Parts Count Variable Voltage Supply ■ Low Output Voltage Power Supplies |
