UC3834 描述
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.
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.
UC3834 特性
- 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
- Under And Over-Voltage Fault Alert With Programmable Delay
- Over-Voltage Fault Latch With 100mA Crowbar Drive Output
