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 T

= 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.
