3.4.5

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.

3.4.6

Reset output

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

flows into the pin. 4V ≤ VSREG ≤ 28V; Tj = -40 °C to 150 °C, unless otherwise specified.

1. Nominal capacitor value required for stability of the regulator. Tested with 220 nF ceramic (+/- 20%). Capacitor must be

located close to the regulator output pin. A 2.2 µF capacitor is recommended to minimize the DPI stress in the application.
