UC1834-DIE  
SLOS898 NOVEMBER 2014  
UC1834-DIE High Efficiency Linear Regulator  
1 Features  
3 Description  
The UC1834-DIE integrated circuit is optimized for  
the design of low input-output differential linear  
regulator. A high-gain amplifier and sink or source  
drive outputs facilitate high-output current designs,  
which use an external pass device. With both positive  
and negative precision references, either polarity of  
regulator can be implemented. A current sense  
amplifier with a low, adjustable threshold can be used  
to sense and limit currents in either the positive or  
negative supply lines.

2 Applications  
Wireless LAN  
In addition, the UC1834-DIE has a fault monitoring  
circuit which senses both undervoltage and  
overvoltage fault conditions. After a user defined  
delay for transient rejection, this circuitry provides a  
fault alert output for either fault condition. In the  
overvoltage case, a crowbar output is activated. An  
overvoltage latch maintains the crowbar output and  
can be used to shutdown the driver outputs. System  
control to the device can be accommodated at a  
single input, which will act as both a supply reset and  
remote shutdown terminal. These die are protected  
against excessive power dissipation by an internal  
thermal shutdown function.

(2) Processing is per the Texas Instruments space production baseline and is in compliance with the Texas Instruments Quality Control  
System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room temperature  
only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not warranted. Visual  
Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
