Note 1: Temperature coefficient is measured by the box method; i.e., the maximum ∆VOUT is divided by ∆T x VOUT.
Note 2: Line regulation (∆VOUT / (VOUT x ∆VIN)) and load regulation (∆VOUT/(VOUT x ∆IOUT)) 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 TA = +25°C by measuring VOUT before and after changing temperature by +25°C
using the PDIP package.
