Texas Instruments LM2576x SIMPLE SWITCHER ® Voltage Stabilizer
The Texas Instruments LM2576x SIMPLE SWITCHER ® voltage regulator is a single-chip integrated circuit that provides all active functions for step-down switch voltage regulators. These regulators can drive 3A loads with excellent line and load adjustment rates. The LM2576x device provides fixed output voltage and adjustable output versions of 3.3V, 5V, 12V, and 15V. The Texas Instruments (TI) LM2576x regulator can efficiently replace the popular three terminal linear regulator. These regulators have efficient TTL shutdown function, which can significantly simplify the design of switch mode power supplies.
