LM2575T-ADJG

The LM2575T-ADJG is a step-down Switching Regulator for use with on-card switching regulators. The LM2575 series buck switching regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step-down switching regulator (buck converter). All circuits of this series are capable of driving a 1A load with excellent line and load regulation. This device is available in fixed output voltage of 3.3, 5, 12, 15 and an adjustable output version. This regulator was designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2575 are offered by several different inductor manufacturers. Since the LM2575 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages.

• Maximum over line and load conditions
• Requires only 4 external components
• TTL shutdown capability and low power standby mode
• High efficiency
• Uses readily available standard inductors
• Thermal shutdown and current limit protection
