regulator 1
This regulator is automatically enabled after the power-on process is complete. It stays enabled until the
power-off condition occurs. Regulator 1 supplies power to the microprocessor. The nominal output voltage is
2.8 V, and the maximum output current is 150 mA. It requires an output capacitor in the range of 4.7
F–10 F
with an equivalent serial resistance (ESR) less than 6
.
regulator 6
This regulator output voltage can be enabled by I2C/SPI by attaching the CONT terminal to VDD. Attaching
CONT to GND makes this regulator automatically enabled with power on. The output voltage is programmed
by I2C/SPI. The maximum out current of 100 mA requires an output capacitor in range of 4.7
F–10 F, with
ESR in the range of 1
–6 . The output voltage ranges from 2.5 V to 3 V.
regulators 2, 3, 4, and 5
Regulators 2, 3, 4, and 5 are output voltages programmed and enabled by I2C. The output voltage ranges from
2.3 V to 3 V in 100-mV steps. The maximum output current for regulators 2 and 3 is 80 mA, for regulator 4 it
is 120 mA, and for regulator 5 it is 150 mA. The default output voltage for all regulators is 3 V. These regulators
have very low output noise; this noise level is suitable for powering up the RF block, which requires an output
capacitor in the range of 4.7
F–10 F with an ESR less than 6 .
vibrator driver
The TWL2213 device has incorporated a vibrator driver with selectable output voltage and current. This
integrated vibrator driver has the same feature as the other load dropout (LDO) regulators. The vibrator is
enabled by I2C. The output voltage can be selected by tying the SEL terminal to VDD or GND. If the SEL terminal
is tied to VDD, the output voltage is set to 3 V. If the SEL terminal is tied to GND, the output voltage is set to 1.3
V.
