Specifications subject to change without notice.
Initial accuracy includes temperature hysteresis effect.
Line and load regulation specifications include the effect of self-heating.
Long-term drift is guaranteed by 1000 hours life test performed on three independent wafer lots at 125 °C, with an LTPD of 1.3.
For proper operation, a 1 µF capacitor is required between the output pin and the GND pin of the device.
TCV
Guaranteed by characterization.
Line and load regulation specifications include the effect of self-heating.
