High Efficiency Linear Regulator

FEATURES

DESCRIPTION

•

Minimum VIN - VOUT Less Than

0.5V At 5A Load With External

Pass Device

The UC1834 family of integrated circuits is optimized for the design of low

input-output differential linear regulators. A high gain amplifier and 200mA

sink or source drive outputs facilitate high output current designs which use

an external pass device. With both positive and negative precision refer-

ences, either polarity of regulator can be implemented. A current sense am-

plifier with a low, adjustable, threshold can be used to sense and limit

currents in either the positive or negative supply lines.

•

Equally Usable For Either Positive

or Negative Regulator Design

Adjustable Low Threshold Current

Sense Amplifier

In addition, this series of parts has a fault monitoring circuit which senses

both under and over-voltage fault conditions. After a user defined delay for

transient rejection, this circuitry provides a fault alert output for either fault

condition. In the over-voltage case, a 100mA crowbar output is activated.

An over-voltage latch will maintain the crowbar output and can be used to

shutdown the driver outputs. System control to the device can be accom-

modated at a single input which will act as both a supply reset and remote

shutdown terminal. These die are protected against excessive power dissi-

pation by an internal thermal shutdown function.
