3 Description

The TL4050-Q1 family 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-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 an

application. Packaged in the space-saving SOT-23-3

and SC-70 packages and requiring a minimum current

of 45μA (typical), the TL4050-Q1 also is designed for

portable applications.

The TL4050x-Q1 characterization is for operation over

an ambient temperature range of –40°C to 125°C.
