描述 Description

The TL4050-Q1 family of shunt voltage references are versatile easy-to-use references suitable 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 ensure a stable output voltage over a wide range of operating currents and temperatures.The TL4050-Q1 is available 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 available to designers in choosing the best cost-to-performance ratio for their applications. Packaged in the space-saving SOT-23-3 and SC-70 packages and requiring a minimum current of 45?μA?(typical), the TL4050-Q1 also is ideal for portable applications.The TL4050x-Q1 characterization is for operation over an ambient temperature range of –40°C to 125°C.
