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
OUT
/ (V
OUT
x ∆V

)) 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.
Note 3: Noise specifications are guaranteed by design.
Note 4: Temperature hysteresis is specified at T
A
= +25°C by measuring V

before and after changing temperature by +25°C.
