LM2576T Adjustable StepDown Switching Regulator

LM2576T Adjustable step down voltage regulator in TO220 (5) package

The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable output version.

LM2576 Voltage regulator are designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2576 voltage regulator are offered by several different inductor manufacturers.

Since the LM2576 converter IC is a switch−mode power supply, its efficiency is significantly higher in comparison with popular three−terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heat sink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch−mode power supplies. The LM2576 adjustable voltage regulator features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to 125°C). External shutdown is included, featuring 80 uA (typical) standby current. The output switch includes cycle−by−cycle current limiting, as well as thermal shutdown for full protection under fault conditions.

We have various types of Voltage Regulator IC's. Check our complete collection of Voltage Regulator IC's.
