description
The UC382 is a low-dropout-linear regulator providing a quick response to fast load changes. Combined with
its precision onboard 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 450 mV maximum at 100°C and 350 mV typical at 3-A load.
The onboard bandgap reference is stable with temperature and scaled for a 1.2-V input to the internal-power
amplifier. The UC382 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.

pin descriptions
ADJ: In the adjustable version, the user programs the output voltage with two external resistors. The resistors
should be 0.1% for high accuracy. The output amplifier is configured as a non-inverting-operational amplifier.
The resistors should meet the criteria of R3 || R4 < 100 Ω. Connect ADJ to VOUT for an output voltage of 1.2 V.
Note that the point at which the feedback network is connected to the output is the Kelvin sense point. For -1,
-2, and -3 versions, ADJ pin is tied to VOUT to obtain specified output voltage.
GND: For accurate results, the GND pin should be referenced to the load ground.
VB: Supplies power to all circuits of the regulator except the collector of the output-power transistor. The 2-V
headroom from VB to VOUT allows the use of a Darlington output stage for inherently-low-output impedance
and fast response. (Dropout is derated for junction temperatures below 0°C.)
VIN: Supplies the current to the collector of the output-power transistor only. The dropout (VIN−VOUT) is under
100 mV for light loads; maximum dropout is 450 mV at 3 A for TJ = 0°C to 100°C. (Dropout is derated for junction
temperatures over 100°C.) At full load, the majority of the VB current is going to the load.
VOUT: This pin should be connected to the load via a low impedance path. Avoid connectors which add
significant inductance and resistance. Note that even though a Kelvin sense is available through a 5-pin
package, care must be taken since voltage drops along wire traces add to the dropout voltage.

APPLICATION INFORMATION
The UC382 is easy to use. The adjustable version requires two 0.1% resistors to set the output voltage. The
fixed versions of the UC382 require no external resistors. All versions of the UC382 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 UC382 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 UC382 with at least 100 µF of high-quality tantalum or Sanyo OSCON capacitors
close to the VOUT pin for maximum stability. Many applications involving Ultra-Fast 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 UC382 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 450 mV is measured at the pins and does not include additional
drops due to trace resistance. The minimum load current is 10 mA.
Two or more UC382’s may be used in parallel. While stable, this arrangement does degrade the transient
response.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.
