∆V
OT specification applies trimmed to +5.000V or untrimmed.
(3) TCVO is defined as ∆VOT divided by the temperature range.
(4) Line and load regulation specifications include the effect of self heating.
(5) Sample tested.
(6) 10k
Ω potentiometer connected between V
OUT and ground with wiper connected to Trim pin. See figure on page 1.
(7) Pin 3 is insensitive to capacitive loading. The temperature voltage will be modified by 7mV for each
µA of loading.
