STMicroelectronics ST1S03APUR is a high-performance buck switching regulator IC designed for efficient power conversion in a compact 6-DFN (3x3) exposed pad package. This positive adjustable output device delivers up to 1.5A of output current, with an adjustable output voltage ranging from 0.8V to 4.79V, derived from an input voltage range of 3V to 5.5V. Featuring a high switching frequency of 1.5MHz, the ST1S03APUR enables the use of small external components, contributing to a reduced solution size. The device operates within an ambient temperature range of 0°C to 125°C. Its surface mount type and buck topology make it suitable for various applications, including portable electronics, power management in consumer devices, and industrial control systems. The ST1S03APUR is supplied on tape and reel (TR).
