Turn-On Time
The ISL21060 devices have low supply current and thus the
time to bias-up internal circuitry to final values will be longer
than with higher power references. Normal turn-on time is
typically 300µs. Circuit design must take this into account
when looking at power-up delays or sequencing.
Temperature Coefficient
The limits stated for temperature coefficient (tempco) are
governed by the method of measurement. The overwhelming
standard for specifying the temperature drift of a reference is to
measure the reference voltage at two temperatures take the
total variation, (V
extremes of measurement (T
divided by the nominal reference voltage (at T = +25°C) and

VOUT Kelvin Sensing
The voltage output for the ISL21060 has both a force and a
sense output. This enables remote kevin sensing for highly
accurate voltage setting with long traces and higher current
loads. The VOUTF (force) can be routed to the load with the
shortest, widest trace possible. The VOUTS (sense) is routed
with a narrower trace to the point of the actual load where it is
connected to the VOUTF trace.
The VOUTF and VOUTS traces must always be connected.
If there is only a short trace to the load or even a very light
load, then they can be connected at or near the ISL21060
device.
