LM2575T Adj 1A Switching Voltage Regulator [SOLD OUT] 
LM2575TSemtech 

 
10 for $3.25 
25 for $6.25 
100 for $16.95 
 
  • New, not used before.
  • LM2575T-Adj
  • 1A Miniconverter Switching Regulator
  • Manufacturer: Semtech
  • Package: TO-220

DESCRIPTION: The LM2575 series switching regulators are monolithic integrated circuits designed for use in "buck" or "buck/boost" regulator applications requiring accurate output voltages over combined variations of line, load and temperature. This unique series greatly simplifies switching power supply design. The LM2575 has a maximum output current of 1A.

The LM2575 series of miniconverters include a switching regulator and compensation network all within the same package. Just add a choke, catch diode and two capacitors to obtain an efficient DC-to-DC converter. The current limit and thermal shutdown features of the LM2575 series fully protect the device against overstress conditions.

The LM2575 series offers an alternative to popular 3 terminal linear regulators by providing higher efficiency with reduced heatsink size. In many applications a heat sink will not be required.

FEATURES:
  • Pin for pin replacement for National's LM2575 series.
  • DC-to-DC buck or buck/boost converter requiring only 4 support components.
  • Adjustable voltages
  • Wide input voltage range, 4V to 40V
  • Inhibit/enable control pin
  • Industrial temperature range
  • TO-220 package
APPLICATIONS:
  • Micro controller power supplies
  • Medical equipment
  • Industrial power supplies
  • Instrumentation power supplies
