37.11.1 Voltage Regulator Characteristics
| Symbol | Parameter | Conditions | Min. | Typ. | Max. | Units |
|---|---|---|---|---|---|---|
| VDDCORE | DC calibrated output voltage | Voltage regulator normal mode | 1.1 | 1.23 | 1.30 | V |
Note: Supplying any external components using the VDDCORE
pin is not allowed to assure the integrity of the core supply voltage.
| Symbol | Parameter | Conditions | Min. | Typ. | Max. | Units |
|---|---|---|---|---|---|---|
| CIN(1) | Input regulator capacitor, between VDDIN and GND | Ceramic dielectric X7R | - | 10 | - | µF |
| - | 100 | - | nF | |||
| COUT(2) | Output regulator capacitor, between VDDCORE and GND | - | 0.8 | 1 | - | µF |
| ESR Cout | External Series Resistance of Cout | - | - | 1 | Ω | |
Note: 1. 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.
Note: 2. It is recommended to use ceramic or solid tantalum capacitor with low ESR <= 1
ohms.
