February 12, 2016 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 В±0.2%
accurate reference. The ISL21010 provides up to 25mA output
current sourcing with low 150mV dropout voltage. Features Reference output voltages . 1.024V, 1.25V, 1.5V,
2.048V, 2.5V, 3.0V, 3.3V, 4.096V Precision 0.2% initial accuracy Applications Input voltage range:
-ISL21010-10, -12, -15 -20 -ISL21010-25 .
-ISL21010-30 -ISL21010-33 -ISL21010-41 Battery management/monitoring Output current source capability 25mA Low power standby voltages Operating temperature range . .-40В°C to +125В°C Portable instrumentation Consumer/medical electronics Output voltage noise (VOUT = 2.048V) 58ВµVP-P
(0.1Hz to 10Hz) Lower cost industrial and instrumentation Supply current . .48ВµA (typ) Power regulation circuits Tempco . 50ppm/В°C Control loops and compensation networks Package . 3 Ld SOT-23 LED/diode supply Pb-free (RoHS compliant) 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. 2.2V to 5.5V
