Introduction :

LM2575T-5 (LM2575 Step-Down 5V Voltage Regulator)

 LM2575 series of regulators are monolithic integratedcircuits that provide all the active functions for a step-down(buck) switching regulator, capable of driving a 1A load withexcellent line and load regulation. These devices are avail-able in fixed output voltages of 3.3V, 5V, 12V, 15V, and anadjustable output version.

Features :

• Fixed output voltage : 5 V.
  
• Guaranteed 1A output current.
• Wide input voltage range : up to 40V .
  
• Requires only 4 external components.
• 52 kHz fixed frequency internal oscillator.
• TTL shutdown capability, low power standby modenHigh efficiency.
• Uses readily available standard inductors.
• Thermal shutdown and current limit protection.
