Fixed voltage, 0.1%, 50-ppm/°C precision micropower shunt voltage reference

The TL4050 series of shunt voltage references are versatile easy-to-use references designed for a wide array of applications. The two-terminal fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to maintain a stable output voltage over a wide range of operating currents and temperatures.

The TL4050 is offered in three initial tolerances, ranging from 0.1% (maximum) for the A grade to 0.5% (maximum) for the C grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for any application. Packaged in the space-saving SOT-23-3 and SC-70 packages and requiring a minimum current of 45µA (typical), the TL4050 also is an excellent choice for portable applications.

The TL4050xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The TL4050xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.
