Micropower Voltage Reference

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.
