ELECTRICAL CHARACTERISTICS VCC = 5.0 V, FBRTN = GND, EN = VCC, VVID = 0.50 V to 1.5000 V, PSI = 1.05 V,
DPRSLP = GND, DPRSTP= 1.05 V, LLSET = CSREF, TA = −10°C to 100°C, unless otherwise noted (Note 1). RREF = 80 kW.
Current entering a pin (sunk by the device) has a positive sign.

1. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC).
2. Guaranteed by design or bench characterization, not production tested.
