The LT ? 3082 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 bene?ts
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 ?ow.
A key feature of the LT3082 is the capability to supply a
wide output voltage range. A precision “0” TC 10μA ref-
erence 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.
