Rev. 1.1, 2012-03-08

3.1.2

Voltage Regulator 1.5V (VDDC)

This module represents the 1.5 V voltage regulator, which serves as core supply for the 8-bit µC and other chip

internal analog 1.5 V functions (e.g. 8 Bit ADC). To further reduce the current consumption of the 8-bit MCU during

Stop Mode the output voltage is optionally reduced to 0.9 V.

Features

•

1.5 V low-drop voltage regulator

•

Optional 0.9 V in Stop Mode

•

Current limitation

•

Overcurrent monitoring and shutdown with MCU signalling (interrupt)

•

Overvoltage monitoring with MCU signalling (interrupt)

•

Undervoltage monitoring with MCU signalling (interrupt)

•

Pull-down current source at the output for Sleep Mode (100 μA)

The output capacitor CVDDC is mandatory to ensure a proper regulator functionality.
