DATASHEET 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. • Reference output voltages . . . . . . . . . . . 1.024V, 1.25V, 1.5V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V • Precision 0.2% initial accuracy 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. • Input voltage range: - ISL21010-10, -12, -15 -20 . . . . . . . . . . . . . . . . - ISL21010-25 . . . . . . . . . . . . . . . . . . . . . . . . . . . - ISL21010-30. . . . . . . . . . . . . . . . . . . . . . . . . . . . - ISL21010-33. . . . . . . . . . . . . . . . . . . . . . . . . . . . - ISL21010-41. . . . . . . . . . . . . . . . . . . . . . . . . . . .

For JC, 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.

Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. 9. 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. 10. Dropout Voltage is the minimum VIN - VOUT differential voltage measured at the point where VOUT drops 1mV from VIN = nominal at TA = +25°C. 11. 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.

VOUT vs NOISE, 0.1Hz TO 10Hz Submit Document Feedback 32 FN7896.3 January 8, 2015 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 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. 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 due to these die stresses. It is normally best to place the device 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 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 multilayer 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. 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.
