200mA Single Resistor Low Dropout Linear Regulator

Description

The LT3082 is a 200mA 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, this regulator benefits many applications requiring high current, adjustability to zero and no heat sink. The LT3082 withstands reverse input voltages and reverse output-to-input voltages without reverse-current flow.A key feature of the LT3082 is the capability to supply a wide output voltage range. A precision "0" TC 10μA reference current source drives a single resistor to program the output voltage to any level between zero and 38.5V. The LT3082 is stable with only 2.2μF of capacitance on the output; the IC uses small ceramic capacitors that do not require additional ESR as is common with other regulators.Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting. The LT3082 is offered in the thermally enhanced 8-lead TSOT-23, 3-lead SOT-223 and 8-lead 3mm × 3mm DFN packages.ApplicationsAll-Surface Mount Power SupplyPost Regulator for Switching SuppliesLow Parts Count Variable Voltage SupplyLow Output Voltage SupplyBattery Powered Regulator
