LM2596 Voltage Regulator

The LM2596 is a highly efficient, 3-A step-down (buck) switching voltage regulator. TO-220 refers to the physical, 5-pin transistor package used to house the chip, which features a metal tab for efficient heat dissipation.

• Function: Steps down a higher input voltage to a lower, stable output voltage.
• Input Voltage: Up to 40 V.
• Output Voltage: Available in fixed (3.3 V, 5 V, 12 V) and Adjustable (1.2 V to 37 V) versions.
• Output Current: Capable of driving up to 3 A continuously.
• Efficiency: High efficiency (up to 92%), making it much cooler than linear regulators.
