高英法fi效率线性稳压器 High Efficiency Linear Regulator
DESCRIPON
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.
FEATURES
• 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
