APPLICATION INFORMATION
The UC385 is easy to use. The adjustable version requires two resistors to set the output voltage. The fixed
versions of the UC385 require no external resistors. All versions of the UC385 require decoupling capacitors
on the input and output. In a typical application, VB and VIN are driven from switching power supplies which
may have large filter capacitors at their outputs. If the UC385 is further than 12 inches from the power supply,
it is recommended to add local decoupling as close as possible to the linear regulator.
Decouple the output of the UC385 with at least 100
µF of high quality tantalum or Sanyo OSCON capacitors
close to the VOUT pin for maximum stability. Many applications involving ultrafast GTL or BTL applications
require additional capacitance close to the load. The exact amount will vary according to speed and magnitude
of the load transients and the tolerance allowed for transients on VOUT. When specifying the decoupling
capacitors, the series resistance of the capacitor bank is an important factor in its ability to filter load transients.
The UC385 allows for Kelvin sensing the voltage at the load. This improves regulation performance and
eliminates the voltage drops due to wire trace resistance. This voltage drop must be added to the headroom
(VIN to VOUT and VB to VOUT). The dropout of 350 mV is measured at the pins and does not include additional
drops due to trace resistance.
