description

The UC385 is a low dropout linear regulator providing a quick response to fast load changes. Combined with

its precision onboard reference, the UC385 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 490 mV maximum and 350 mV typical at 5-A load (0°C to 100°C).

The onboard bandgap reference is stable with temperature and scaled for a 1.2 V input to the internal power

amplifier. The UC385 is available in fixed output voltages of 1.5 V, 2.1 V, or 2.5 V. 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 1.2 V.
