The ISL21010 is a precision, low dropout micropower bandgap

voltage reference in a space-saving SOT-23 package. It

operates from a single 2.2V to 5.5V supply (minimum voltage

is dependent on voltage option) and provides a ±0.2

accurate reference. The ISL21010 provides up to 25mA output

current sourcing with low 150mV dropout voltage.

Output voltage options include 1.024V, 1.2V, 1.5V, 2.048V,

2.5V, 3.0V, 3.3V and 4.096V. The low supply current and low

dropout voltage combined with high accuracy make the

ISL21010 ideal for precision battery powered applications.
