Description The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. Features Adjustable Version Output Voltage Range: 1.2-V to 37-V ± 4% Maximum Over Line and Load Conditions Available in TO-220 and TO-263 Packages 3-A Output Load Current Input Voltage Range Up to 40 V Requires Only 4 External Components Excellent Line and Load Regulation Specifications 150-kHz Fixed-Frequency Internal Oscillator TTL Shutdown Capability Low Power Standby Mode, IQ, Typically 80 μA High Efficiency Uses Readily Available Standard Inductors Thermal Shutdown and Current-Limit Protection Application Simple High-Efficiency Step-Down (Buck) Regulator On-Card Switching Regulators Positive to Negative Converter

• Easy to DIY: Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step down voltage. (Factory default stays a high voltage, you need to "rotate about 7-15 circles" before the voltage starts ramping down, 1 circle means +/- 1V)
• Applications: Widely used for DIY Mobile power, Contstant power supply, Power buggies, Communications equipment power supply, Motor controllers, Drills, Led etc.
