41.10.1 Voltage Regulator Characteristics

Table 41-17. Voltage Regulator Electrical Characteristics
Parameter	Conditions	Symbol	Min.	Typ.	Max.	Unit
DC calibrated output voltage	Voltage regulator normal mode	V_DDCORE	1.1	1.23	1.3	V

Note: Supplying any external components using V_DDCORE pin is not allowed to assure the integrity of the core supply voltage.

Table 41-18. Decoupling requirements
Symbol	Parameter	Conditions	Min.	Typ.	Max.	Units
C_IN⁽¹⁾	Input regulator capacitor, between V_DDIN and GND	Ceramic dielectric X7R	-	10	-	µF
C_IN⁽¹⁾	Input regulator capacitor, between V_DDIN and GND	Ceramic dielectric X7R	-	100	-	nF
C_OUT⁽²⁾	Output regulator capacitor, between V_DDCORE and GND	-	0.8	1	-	µF
ESR Cout	External Series Resistance of Cout		-	-	1	Ω

Note:

It is recommended to use ceramic X7R capacitor with low-series resistance. Refer to Figure 45-1 for a typical circuit connections of the decoupling capacitor.
It is recommended to use ceramic or solid tantalum capacitor with low ESR <= 1 ohms.
