The LM2598S-3.3 from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving a 1A load with excellent line and load regulation. This device features a fixed 3.3V output voltage and operates at a 150kHz internal oscillator frequency, allowing for smaller filter components compared to lower frequency regulators.
The regulator accepts an input voltage range from 4.5V to 40V and delivers a stable 3.3V output. Key features include thermal shutdown and current limit protection for enhanced reliability. It is available in a surface mount DDPAK/TO-263-7 package, suitable for various electronic designs.
This series of regulators requires a minimum number of external components, making them simple to use. They include internal frequency compensation and offer features like shutdown/soft-start and an out-of-regulation error flag. The LM2598S-3.3 is well-suited for applications requiring efficient power conversion in a compact form factor.
