The advanced design of TI’s LM4128 eliminates the need for an external stabilizing capacitor

The LM4128 precision voltage reference from Texas Instruments is available in an SOT-23 surface-mount package, making it the ideal choice for engineers working in space-critical applications.

The unique design of this particular precision voltage reference allows for the elimination of an external stabilizing capacitor, yet still ensures stability with capacitive loads up to 10 µF. As a result, the LM4128 is super easy to use.

Another advantage to using the LM4128 is that this series provides lower power consumption than shunt references. This is due to the fact that they do not have to idle the maximum load current when under no load conditions. Couple this advantage with its low quiescent current (60 µA), and the low dropout voltage (400 mV), it’s obvious the LM4128 is ideal for battery-powered solutions.

If you’re interested in the LM4128, do note it comes in four grades, (A, B, C, and D) — the best grade devices (A) have an initial accuracy of 0.1% with ensured temperature coefficient of 75 ppm/°C or less, while the lowest grade parts (D) have an initial accuracy of 1.0% and a tempco of 100 ppm/°C.
