(1) VBridge = 4.3V, IS/R = 3.2A, VOUT = VSET – VRESET

(2) If VBridge = 8.0V, IS/R = 2.0A, lower S/R current leads to greater output variation.

(3) Effective current from power supply is less than 1mA.

(4) Not tested in production, guaranteed by characterization.

(*) Tested at 25° C except otherwise stated.
