2 / 7 page  No. 6656-2/7 LB11981 Parameter Symbol Conditions Ratings Unit Supply voltage 1 VCC *8 (5) to 28 V Supply voltage 2 VCCM 8 to 28 V Operating Conditions at Ta = 25°C Note: * This device should normally be used with VCC ≥ 8 V. If used with 5 V ≤ VCC < 8 V, short the VCC and VREG pins together. Note that in this case the electrical characteristics of the device become more easily influenced by fluctuations in the VCC supply voltage.
