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 am-plifier with a low, adjustable, threshold can be used to sense and limit currents in either the positive or negative supply lines. 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 ac com-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.
