UCC381-3/-5/-ADJ  
Low Dropout 1 Ampere Linear Regulator Family  
DESCRIPTION  
FEATURES  
The UCC381-3/-5/-ADJ family of positive linear series pass regulators is  
tailored for low drop out applications where low quiescent power is impor-  
tant. Fabricated with a BiCMOS technology ideally suited for low input to  
output differential applications, the UCC381 will pass 1A while requiring  
only 0.5V of input voltage headroom. Dropout voltage decreases linearly  
with output current, so that dropout at 200mA is less than 100mV. Quies-  
cent current is always less than 650µA. To prevent reverse current conduc-  
tion, on-chip circuitry limits the minimum forward voltage to typically 50mV.  
Once the forward voltage limit is reached, the input-output differential volt-  
age is maintained as the input voltage drops until undervoltage lockout dis-  
ables the regulator.

Adjustable Output Voltage Version  
Fixed Versions for 3.3V and 5V  
Outputs  
UCC381-3 and UCC381-5 versions have on-chip resistor networks preset  
to regulate either 3.3V or 5.0V, respectively. Furthermore, remote sensing  
of the load voltage is possible by connecting the VOUTS pin directly at the  
load. The output voltage is then regulated to 1.5% at room temperature and  
better than 2.5% over temperature. The UCC381-ADJ version has a regu-  
lated output voltage programmed by an external user-definable resistor ra-  
tio.
