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.
