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.

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,
ISL21010CFH330, ISL21010CFH333, ISL21010CFH341 device pages. For more information about MSL, see TB363.

NOTES:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization, and/or design.
8. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the
temperature range; in this case, -40°C to +125°C = +165°C.
9. Dropout Voltage is the minimum VIN - VOUT differential voltage measured at the point where VOUT drops 1mV from VIN = nominal at TA = +25°C.
10. Thermal Hysteresis is the change of VOUT measured at TA = +25°C after temperature cycling over a specified range, TA. VOUT is read initially at
TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference between
the initial VOUT reading and the second VOUT reading is then expressed in ppm. For TA = +165°C, the device under test is cycled from +25°C to
-40°C to +125°C to +25°C.
11. 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.

ISL21010
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
58µVP-P to 100µVP-P (VOUT = 2.048V, 3.0V, and 3.3V) benefiting
precision, low noise portable applications such as handheld
meters and instruments.
Data converters in particular can use the ISL21010 as an
external voltage reference. Low power DAC and ADC circuits
achieve maximum resolution with lowest noise. The ISL21010
maintains output voltage during conversion cycles with fast
response, although it is helpful to add an output capacitor,
typically 1µF.
Board Assembly Considerations
Bandgap references provide high accuracy and low temperature
drift but some PCB assembly precautions are necessary. Normal
output voltage shifts of 100µV to 4mV can be expected with
Pb-free reflow profiles or wave solder on multilayer FR4 PCBs.
Avoid excessive heat or extended exposure to high reflow or wave
solder temperatures; this can reduce device initial accuracy.
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 5) is for 0.1µF
(0.22µF for 1.024V option) capacitive load. Larger values reduce
the output noise level.
Board Mounting Considerations
For applications requiring the highest accuracy, review the board
mounting location. The ISL21010 uses a plastic SOIC package,
which subjects the die to mild stresses when the Printed Circuit
Board (PCB) is heated and cooled and slightly changes the
shape. Placing the device in areas subject to slight twisting
degrades the accuracy of the reference voltage due to these die
stresses. It is normally best to place the device near the edge of a
board, or on the shortest side because the axis of bending is
most limited at that location. Mounting the device in a cutout
also minimizes flex. Mounting the device on flexprint or
extremely thin PCB material causes reference accuracy loss.
