Introduction
The ISL21080XXEV1Z evaluation board is designed to measure
the performance of the nano power ISL21080 voltage reference.
The reference comes in a wide selection of output voltages
ranging from 0.9V to 5.0V, and an initial accuracy as low as 0.2%
(3.0V to 5.0V options). With a typical supply current of 500nA or
less, the ISL21080 is ideal for extending battery life while
reducing cost for general purpose portable applications.
The evaluation board includes voltage input test points (V
GND) for a power supply input, as well as a pair of test points for
the output (V
damper network can connect to V
surface mount or through-hole style resistors for output load
testing.

ISL21080XXEV1Z Board
The schematic of the evaluation board is shown in Figure 5. The
ISL21080XXEV1Z contains the ISL21080 voltage reference (U
input decoupling capacitors (C
The power supply leads attach to TP1 and TP2 (V
output is measured at test points TP3 and TP4 (V
The R-C damper network is populated and can be connected to
the reference output by adding a shunt to the R-C jumper (J
The damper network improves stability by reducing transient
load ringing with high value (>0.47µF) capacitors.
