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.

website at www.ti.com.

(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.
