The internal voltage regulators are dual low-drop voltage regulators that can supply loads up to
input voltage up to V
circuitry, featuring two SPI configurable power-on timing (t
monitoring, the device is well suited for microcontroller supply. The design enables stable operation even with
ceramic output capacitors down to 470nF, with ESR < 1 Ω @ f = 10 kHz. The device is designed for automotive
applications, therefore it is protected against overload, short circuit, and overtemperature conditions.
