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.

NOTES:
1. See
TB347
for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate
plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), see the
ISL21010DFH310, ISL21010DFH312, ISL21010CFH315, ISL21010CFH320, ISL21010CFH325,
