ST1S12GR ST DC-DC Converter | TSOT-23-5 | 3A Output, 2.5V-5.5V Input

Product Overview

The ST1S12GR is a high-efficiency step-down DC-DC converter from STMicroelectronics, designed for compact power management solutions. Housed in a TSOT-23-5 package, it delivers up to 3A output current with an input voltage range of 2.5V to 5.5V. The device features a fixed 1.5MHz switching frequency, enabling small external components and low output ripple. With integrated power switches and a low dropout operation, the ST1S12GR is ideal for space-constrained applications requiring high power density.
