TL4051BQDBZR TI Voltage Reference | SOT-23-3 | 1.225V, ±0.2%

Product Overview

The TL4051BQDBZR is a precision micropower shunt voltage reference from Texas Instruments, offering a fixed 1.225V output with an initial accuracy of ±0.2% (B grade). Housed in a compact SOT-23-3 package, it is designed for low-power and space-constrained applications. The device operates over a wide current range from 45 µA to 12 mA, with a typical temperature coefficient of 20 ppm/°C. Its low dynamic impedance and excellent long-term stability make it ideal for precision analog systems.
