UC3834 High Efficiency Linear Regulator
FEATURES DESCRIPTION Minimum VIN -VOUT Less Than
0.5V At 5A Load With External
Pass Device Equally Usable For Either Positive
or Negative Regulator Design Adjustable Low Threshold Current
Sense Amplifier 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 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. Under And Over-Voltage Fault Alert
With Programmable Delay Over-Voltage Fault Latch With
100mA Crowbar Drive Output BLOCK DIAGRAM 6/94 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 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. UC1834
