1. The 0.1% reported in the slope is Typical value.

Voltage regulator V2

The voltages are referred to ground and currents are assumed positive, when the current

flows into the pin. 4.5 V ≤ VS ≤ 28 V; 4.5 V ≤ VSREG ≤ 28 V; Tj = -40 °C to 150 °C, unless

otherwise specified.

In case the V2 regulator works as a classical voltage regulator (default case), the electrical

specifications are reported in Table 11; in case V2 is configured to work as voltage tracker of

V1, the electrical specifications are reported in Table 12.
