Overview
The TS33 family of low power series voltage references, specifically the TS3330AQPR model from STMicroelectronics, is designed to provide stable and precise output voltages. This component boasts an initial accuracy of 0.15% over an extended temperature range of -40 to +125 °C, making it highly suitable for high-precision applications. The ultra-low operating current of 3.9 μA (typical at 25 °C) is a significant advantage for power-restricted designs. The TS33 series is available in various surface mount packages, including QFN8, SOT23-3L, and SOT323-3L, which are ideal for applications where space saving is critical.
