UC182-3 General Description
The UC382 is a low dropout linear regulator providing a quick 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 required to decouple the regulator's output can be significantly decreased when compared to standard LDO linear regulators.
Dropout voltage (VIN to VOUT) is only 450mV maximum at 100°C and 350mV typical at 3A load.
The on-board bandgap reference is stable with temperature and scaled for a 1.200V input to the internal power amplifier. The UC382 is available in fixed output voltages of 1.5V, 2.1V, or 2.5V. The output voltage of the adjustable version can be set with two external resistors. If the external resistors are omitted, the output voltage defaults to 1.2V.
