Note 1: Temperature coefficient is measured by the box method; i.e., the maximum ∆V
OUT
is divided by ∆T x V
OUT
.
Note 2: Line regulation (∆V

/ (V

)) and load regulation (∆V

/ (V

)) are measured with pulses and do
not include output voltage changes due to die-temperature changes.
Note 3: Noise specifications are 100% tested for the 10Hz to 1kHz bandwidth. Contact factory for 100% noise testing in the 0.1Hz
to 10Hz bandwidth.
Note 4: Temperature hysteresis is specified at T
