The LM2575T-ADJ/NOPB from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 1A load with excellent line and load regulation. This adjustable output version offers a voltage range from 1.23V to 37V, with a maximum deviation of ±4% over line and load conditions.
Key features include a fixed 52kHz internal oscillator, TTL shutdown capability for low power standby mode, and thermal shutdown and current limit protection. The device requires minimal external components, simplifying design, and offers high efficiency, often eliminating the need for a heat sink compared to linear regulators.
Packaged in a TO-220-5 through-hole configuration, the LM2575T-ADJ/NOPB operates within a temperature range of -40°C to 125°C. Its design is optimized for use with readily available standard inductors, simplifying the creation of switch-mode power supplies.
