The TL4050 series 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 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 µ A (typ), the TL4050 also is ideal 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.

SLOS486A – JUNE 2007 – REVISED AUGUST 2009 Cathode and Load Currents In a typical shunt-regulator configuration (see Figure 3), an external resistor, RS, is connected between the supply and the cathode of the TL4050. RS must be set properly, as it sets the total current available to supply the load (IL) and bias the TL4050 (IZ).
