ISL21010
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.
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.
