The LM2575T-12/NOPB is part of the LM2575 series of step-down switching regulators from Texas Instruments. These switching regulators are designed to convert a high input DC voltage, such as 12V, 24V or 40V, down to a constant lower output voltage of 12V. The output voltage can be adjusted via a sense pin. The LM2575 series is capable of delivering output currents up to 1.5A and features low ripple noise, making them suitable for a variety of power supply applications. This part is the through-hole version of the LM2575, meaning it is intended for manual connection through mounting holes, rather than onto a circuit board.
