The UC385 is a low dropout linear regulator that responds quickly to fast load changes. It has a precision onboard reference and 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 compared to standard LDO linear regulators. The dropout voltage (VIN to VOUT) is only 490mV maximum and 350mV typical at a 5A load (0°C to 100°C). The onboard bandgap reference is stable with temperature and scaled for a 1.2V input to the internal power amplifier. The UC385 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.
