Notes:
2. The deviation parameters V REF(DEV) and I REF(DEV) are defined as the differences between the maximum and
minimum values obtained over the rated temperature range. The average full-range temperature coefficient of the
reference input voltage, ? V REF , is defined as:
{ V REF ( DEV ) /V REF ( T A = 25°C ) } × 10
? T A
?V REF

( ppm/°C ) = -----------------------------------------------------------------------------------------------------
Z OUT, TOT = -------- ≈ Z OUT × 1 + --------
where ? T A is the rated operating free-air temperature range of the device.
3. The dynamic impedance is defined as |Z OUT | = ? V COMP / ? I LED . When the device is operating with two external
resistors (see Figure 2), the total dynamic impedance of the circuit is given by:
? V R1
? I R2
