Overview
The TS4041DILT-1.2, produced by STMicroelectronics, is a low-power shunt voltage reference designed to provide a stable 1.225V output voltage across the industrial temperature range of -40°C to +85°C. This component is particularly useful in power-restricted designs due to its ultra-low operating current. It is available in the SOT23-3 surface mount package, making it ideal for applications where space is critical.
