Note 1:
Note 2:
Temperature coefficient is measured by the box method; i.e., the maximum
V
OUT
is divided by
T x V
OUT
.
Line regulation (
V
OUT
/ (V
OUT
x
V
IN
)) and load regulation (
V
OUT
/ (V
OUT
x
I
OUT
)) are measured with pulses and do
not include output voltage changes due to die-temperature changes.
Noise specifications are 100% tested for the 10Hz to 1kHz bandwidth. Contact factory for 100% noise testing in the 0.1Hz
to 10Hz bandwidth.
Temperature hysteresis is specified at T
A
= +25°C by measuring V
OUT
before and after changing temperature by +25°C
using the PDIP package.
