(1) The minimum supply voltage for the REF3212 is 1.8V.
(2) Load regulation is using force and sense lines; see the Load Regulation section for more information.
(3) Thermal hysteresis procedure is explained in more detail in the Applications Information TBD section.
(4) If the rise time of the input voltage is less than or equal to 2ms, the ENABLE and IN pins can be tied together. For rise times greater
than 2ms, see the Supply Voltage section.
