Freescale Semiconductor
Table 7
provides the operating parameters for the linear regulator.
NOTE
A pmos regulator is used as a current source in this linear regulator, so a
10 μF capacitor (ESR 0... 5 Ohm) is needed on the output pin (LINOUT) to
integrate the current. Typically, this requires the use of a tantalum type
capacitor.
Table 8
provides the operating parameters for the ADC DC electrical characteristics.
Table 9
provides the DC electrical specifications for the digital pins.
