2.4.5

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.

1. Specified by design, not tested in production.

2. Nominal capacitor value required for stability of the regulator. Tested with 1 µF ceramic (±20%). Capacitor must be located

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