The TL4051 series of shunt voltage references are versatile easy-to-use references suitable for a wide array of
applications. The device is available in a fixed 1.225-V output or an adjustable output whose voltage is
determined by an external resistor divider. The 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 TL4051 is offered in three initial tolerances, ranging from 0.1% (max) for the A grade to 0.5% (max) for the
C grade. Thus, a great deal of flexibility is offered 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 (typ), the TL4051 also is ideal for portable applications.
The TL4051xI is characterized for operation over an ambient temperature range of –40
°C to 85°C. The
TL4051xQ is characterized for operation over an ambient temperature range of –40
°C to 125°C.
