6.5 Electrical Characteristics (continued)

Over 0.85 V ≤ VIN ≤ 7 V, VBIAS ≥ VOUT + 1.6 V (VIN ≤ VBIAS ≤ 14 V & VBIAS ≥ 2.2 V), VOUT (target) ≤ VIN – 1.6 V, IOUT = 1 mA,

COUT = 220 µF(1), RREF = 12.0 kΩ, over operating temperature range (TA = –55°C to 125°C), typical values are at TA = 25°C,

unless otherwise noted; includes RLAT at TA = 25°C if sub-group number is present for QML RHA and SEP devices(2)
