Micropower Voltage Reference
ISL21010
Features
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.

- ISL21010-41. . . . . . . . . . . . . . . . . . . . . . . . . . . . 4.2V to 5.5V
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.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. For θ , the “case temp” location is taken at the package top center.

7. Post-reflow drift for the ISL21010 devices may shift up to 4.0mV based on simulated reflow at 260°C peak temperature, three passes. The system
design engineer must take this into account when considering the reference voltage after assembly.

due to these die stresses. It is normally best to place the device
Applications Information
Micropower Operation
The ISL21010 consumes very low supply current due to the
proprietary bandgap technology. Low noise performance is
achieved using optimized biasing techniques. Supply current is
typically 48µA and noise in the 0.1Hz to 10Hz bandwidth is
near the edge of a board, or the shortest side, as the axis of
bending is most limited at that location. Mounting the device in a
cutout also minimizes flex. Obviously mounting the device on
flexprint or extremely thin PC material will likewise cause loss of
reference accuracy.
Board Assembly Considerations
58µV
to 100µV (V = 2.048V, 3.0V, and 3.3V) benefitting
P-P
P-P OUT
Bandgap references provide high accuracy and low temperature
drift but some PC board assembly precautions are necessary.
Normal Output voltage shifts of 100µV to 4mV can be expected
with Pb-free reflow profiles or wave solder on multi-layer FR4 PC
boards. Precautions should be taken to avoid excessive heat or
extended exposure to high reflow or wave solder temperatures,
this may reduce device initial accuracy.
precision, low noise portable applications such as handheld
meters and instruments.
Data Converters in particular can utilize the ISL21010 as an
external voltage reference. Low power DAC and ADC circuits will
realize maximum resolution with lowest noise. The device
Maintains output voltage during conversion cycles with fast
response, although it is helpful to add an output capacitor,
typically 1µF.
Noise Performance and Reduction
The recommended capacitive load range for the ISL21010 is from
0.1µF to 10.0µF (0.22µF minimum required for 1.024V option) to
ensure stability and best transient performance. Parallel 0.1µF
(0.22µF for 1.024V) and 10µF capacitors can be used to optimize
performance as well. The noise specification stated in the
Electrical Specification tables (starting on page 4) is for 0.1µF
(0.22µF for 1.024V option) capacitive load, and larger values will
reduce the output noise level.
Board Mounting Considerations
For applications requiring the highest accuracy, board mounting
location should be reviewed. The device uses a plastic SOIC
package, which will subject the die to mild stresses when the
Printed Circuit (PC) board is heated and cooled, slightly changing
the shape. Placing the device in areas subject to slight twisting
can cause degradation of the accuracy of the reference voltage
