Functional Block Description
20% in series with the output capacitance is required. The total resistance includes the ESR of the capacitor plus an external
resistance provided by a discrete resistor or PCB circuit trace.
The nominal output voltage of this regulator can be configured through SPI and can be 2.5 V, 2.6 V, 2.7 V, or 2.775 V. The
maximum output current along the external PNP is 250
mA.
