IKSemicon LM2596-ADJ DC-DC Step-Down Voltage Regulator

The LM2596 regulator series is a monolithic integrated circuit that provides all of the active operations for a step-down switching regulator capable of driving a 3A load with excellent line and load control. Multiple variants are available for these devices in 3.3V, 5V, and 12V fixed output voltages and an adjustable output variant.
These regulators are simple to operate because they require only a few external components. The switching frequency of the IL2596 series is 150kHz. A standard 5-lead TO220 package is available. Other features include a guaranteed 4% output voltage tolerance under specified input voltage and output load conditions and a 15% oscillator frequency tolerance. External shutdown is provided, with a typical standby current of 100A.
