The UC382 is a low dropout linear regulator that provides a fast response to fast load changes. Combined with its precision on-board reference, the UC382 excels at driving GTL and BTL buses. Due to its fast response to load transients, the total capacitance of the decoupling regulator can be significantly reduced compared to standard LDO linear outputs. Dropout voltage (VIN to VOUT) is 450mV max only at 100°C and 350mV typical for a 3A load. The upper board bandgap reference is temperature stable and scaled at the input of a 1.200V internal power amplifier. The UC382 offers fixed output voltages of 1.5V, 2.1V or 2.5V. The adjustable output voltage can be set with two external resistor versions. If the external resistor is omitted, the output voltage falls to the default value of 1.2V.
